Project Overview: The Starting Point
Background and Goals
The subject: a 1980s-era, 65-square-foot guest bathroom. It featured a yellowed fiberglass tub, builder-grade vanity, old linoleum flooring, and a dated, flickering light fixture. The homeowner’s goals were clear:
- Modernize the space with a walk-in shower and stylish tile.
- Improve lighting and ventilation.
- Increase storage with a new vanity and shelving.
- Stay within a $14,000 total budget.
Initial Assessment
Before any demolition, the homeowner performed a thorough check for:
- Moisture or mold issues behind and under existing fixtures.
- Plumbing and electrical layout—would moving fixtures be feasible?
- Structural integrity—checking for water-damaged subflooring.
Outcome: No major hidden damage, but a minor leak was discovered at the toilet seal, which would be addressed during demolition.
Budgeting and Cost Breakdown
Setting a Realistic Budget
Bathroom renovations vary widely in cost depending on size, materials, and labor. Here’s how the project’s $14,000 budget was allocated:
- Demolition & Disposal: $900
- Plumbing (rough-in & fixtures): $3,300
- Electrical (lighting & exhaust): $1,100
- Tile & Flooring: $2,800
- Vanity, Countertop & Sink: $2,000
- Shower Glass & Fixtures: $2,500
- Paint & Finishing Materials: $400
- Permits & Inspections: $400
- Contingency Reserve: $1,000
Unexpected Costs
During demolition, minor subfloor repairs and upgraded GFCI outlets were needed, adding $600 to the initial estimates. The homeowner was able to adjust by selecting a slightly less expensive vanity without compromising style or function.
Design and Planning
Layout Choices
To maximize space, the bathtub was replaced with a walk-in shower featuring a linear drain and frameless glass. The vanity shifted six inches to accommodate a larger mirror and extra wall shelving.
Material Selection
- Shower: Porcelain 12″x24″ wall tiles, pebble mosaic floor.
- Floor: Waterproof luxury vinyl plank (LVP) for durability and warmth.
- Vanity: Floating, wall-mounted, with quartz countertop.
- Lighting: LED recessed cans plus a modern sconce above the sink.
- Paint: Mold-resistant satin finish in a cool gray.
Planning Tools
Design software (SketchUp) was used to visualize layout options and material combinations. Pinterest boards helped consolidate inspiration and finalize color palettes.
Permits and Compliance
Understanding Local Requirements
Most municipalities require permits for bathroom remodels involving plumbing or electrical work. The homeowner contacted the city’s building department and confirmed:
- Permits were needed for plumbing and electrical updates.
- Inspections would be required before closing up walls and at final completion.
- All electrical work must comply with the latest NEC (National Electrical Code).
Securing Permits
Permit applications were submitted online. The process required:
- Detailed plans and fixture locations.
- Product specs for shower glass and electrical fixtures.
- Proof of licensed contractor for plumbing (a local requirement).
Permits were issued in five business days, at a cost of $400.
Demolition: Out with the Old
Preparation
Before demolition began, dust barriers and floor protection were installed. The water supply was shut off and breakers for the bathroom were switched off at the panel. A dumpster was rented for debris.
Demolition Steps
- Removed vanity, toilet, and old light fixtures.
- Carefully cut out and disposed of fiberglass tub and surround.
- Peeled up old linoleum and underlayment.
- Inspected subflooring—repaired minor rot near toilet flange.
Plumbing and Electrical Rough-In
Plumbing
With walls open, the plumber rerouted supply lines for the new shower controls and rain head. Drain lines were adjusted to accommodate the linear shower drain. The toilet flange was replaced due to minor corrosion.
Electrical
New 20-amp circuits were installed for the vanity outlet, and all outlets were upgraded to GFCI. Wiring for recessed lighting and the exhaust fan was run through the ceiling joists. The old light switch was replaced with a smart dimmer.
Choosing and Using the Right Tools
Essential Tools for This Project
- Oscillating multi-tool (for precise demolition and cutting openings)
- Wet tile saw (for custom tile cuts)
- Laser level (for layout accuracy)
- Drill/driver set (for fasteners and mounting hardware)
- Shop vac (for continuous dust and debris removal)
- Caulk gun and grout float (for finishing tile work)
Tool Rental vs. Purchase
Specialty tools like the wet tile saw were rented, saving over $400 compared to buying. The homeowner invested in a quality drill/driver set that would see ongoing use for future projects.
Tile, Flooring, and Finishes
Shower Tile Installation
Waterproofing is critical. A liquid membrane (RedGard) was applied to cement backer board before tiling. Tiles were set with a high-flex thinset and spaced with leveling clips for even grout lines. A pebble mosaic was chosen for the shower floor, both for style and slip resistance.
Vanity and Flooring
The floating vanity was mounted to studs with 4″ structural screws. Plumbing connections for the sink and faucet were leak-tested before securing the cabinet. LVP flooring was installed last, running seamlessly under the vanity for a built-in look.
Glass and Hardware
A local glass supplier custom-fabricated the frameless shower enclosure. Hardware was chosen in a matte black finish for a modern touch, and all caulk joints were smoothed for water resistance and aesthetics.
Paint, Lighting, and Final Details
Painting
Walls and ceiling were primed with a stain-blocking primer and finished with mold-resistant satin paint. All trim was given a fresh coat of semi-gloss white for contrast.
Lighting and Accessories
Two LED recessed lights illuminate the shower and vanity, complemented by a dimmable sconce above the sink. Accessories (mirror, towel bars, shelves) were carefully measured and installed into wall anchors.
Inspections and Approvals
City Inspections
The homeowner scheduled plumbing and electrical inspections through the city’s online portal. Both passed with minor notes to add additional nail plates over wiring and to adjust the shower drain’s pitch. After corrections, the final inspection was approved with no issues.
Post-Renovation Maintenance Best Practices
Waterproofing and Mold Prevention
- Wipe down shower walls and floor after each use to reduce moisture.
- Run the exhaust fan for at least 20 minutes after showers.
- Inspect caulk and grout lines monthly and repair any cracks promptly.
- Use a mildew-resistant cleaner on tile and glass surfaces weekly.
Hardware and Fixture Care
- Clean faucet aerators and showerheads every 3-4 months to prevent mineral buildup.
- Tighten loose handles or hardware as needed.
- Check for leaks under the vanity and around the toilet quarterly.
Lighting and Electrical Safety
- Test GFCI outlets monthly.
- Replace LED bulbs with the same wattage and color temperature for consistent lighting.
Lessons Learned: What Worked and What Didn’t
Successes
- Thorough planning and 3D modeling prevented costly layout errors.
- Renting specialty tools saved money and storage space.
- Allocating a contingency fund helped cover surprises without stress.
Challenges
- Permit processing took longer than expected due to city staff shortages.
- Minor mistakes in tile layout required creative adjustments.
- Coordinating schedules with subcontractors led to brief delays.

I noticed you mentioned addressing a minor leak at the toilet seal during demolition. Can you explain how you detected it before opening things up, and what steps you took to fix it once the renovation was underway?
We noticed the minor leak at the toilet seal because there was a faint water stain around the base of the toilet and a slight musty odor, both of which are common signs of a seal issue. Once demolition began, we confirmed the leak and removed the toilet. We cleaned the area thoroughly, replaced the old wax ring with a new one, and ensured the toilet was securely reinstalled to create a watertight seal.
I’m a parent planning a bathroom upgrade, and I’m wondering how much of your $14,000 budget went toward labor versus materials. Did you find any specific ways to save money without sacrificing quality, especially with things like the walk-in shower or storage solutions?
Of the $14,000 budget, about 60% went toward labor and 40% toward materials. For savings, we sourced tiles and fixtures during seasonal sales, and reused existing plumbing to cut costs. Opting for built-in shelves rather than custom cabinetry also helped manage expenses, and choosing a prefabricated walk-in shower base instead of a fully custom one delivered both quality and savings.
For a 65-square-foot bathroom like this one, how long did the entire renovation process take from initial assessment through to completion, and were there any delays that surprised you?
The renovation for this 65-square-foot bathroom took about five weeks from the initial assessment to final completion. This included designing, demolition, plumbing and electrical updates, tiling, and installation of fixtures. There was a surprise delay of about four days due to an unexpected issue with outdated plumbing behind the walls, which required extra repairs before finishing the tiling and installations.
Your budget was set at $14,000 for this renovation. At which stage did you find it most difficult to stick to the budget and were there any areas where you felt it was worth spending extra versus saving?
Sticking to the budget was most challenging during the fixture selection stage, particularly when choosing faucets, lighting, and the shower system. We decided it was worth spending extra on high-quality fixtures and waterproofing materials since they contribute significantly to both style and longevity. On the other hand, we saved by opting for mid-range tiles rather than luxury options and reused the existing vanity with some refinishing.
Did you consider keeping any of the existing features, like the old vanity or light fixture, to save on the $14,000 budget? If so, what made you decide to replace everything instead of refurbishing?
We did consider keeping the old vanity and light fixture to help with the budget, but after assessing their condition, we found they were too worn and didn’t fit the modern style we wanted. Refurbishing would have required extra work and materials, so replacing them ultimately provided better functionality and a cohesive look for the new bathroom.
You touched on checking the plumbing and electrical layout before making design decisions. If the layout hadn’t worked for the new plan, what would have been your backup strategy, and how would that have affected your budget or timeline?
If the existing plumbing or electrical layout hadn’t fit our new design, our backup strategy would have been to reroute pipes or wiring as needed. This typically requires hiring licensed professionals, which could increase costs significantly and extend the timeline by several days or even weeks. We would have updated the budget to include labor, materials, and possible permits, and adjusted the schedule to accommodate inspections and any unexpected challenges.
Given that the bathroom was only 65 square feet, were there any space-saving storage solutions or design choices that really made a difference beyond the new vanity and shelving?
Yes, the renovation included several space-saving ideas besides the new vanity and shelving. The team opted for a wall-mounted toilet, which freed up floor space and made the room feel less cramped. They also used recessed niches in the shower and above the sink for extra storage without taking up any usable space. Light-colored tiles and a frameless glass shower door helped open up the room visually, making it feel larger and less cluttered.
If someone wanted to modernize their bathroom but couldn’t afford a full remodel, which upgrades from your project would you say had the biggest impact on style and function within a smaller budget?
Focusing on fixtures and finishes can make a big difference without a full remodel. In our project, swapping out old faucets, cabinet hardware, and light fixtures updated the look instantly. Adding a fresh coat of paint and installing new mirrors also made the space feel more modern and open. These changes are cost-effective but really help elevate both style and functionality.
How did you prioritize between splurging on nicer tile for the walk-in shower versus sticking to your $14,000 budget overall? Did you have to make any big compromises on the materials or features you originally wanted?
Balancing the budget meant we had to be strategic. We chose to spend more on quality tile for the walk-in shower because it was the focal point, then saved by selecting more affordable flooring and fixtures elsewhere. While we did trim some features, like heated floors and custom cabinetry, the main design and function remained intact thanks to these trade-offs.
As a parent with limited time, I’m curious—how long did the entire renovation process actually take from start to finish, including all the troubleshooting for things like the plumbing and lighting?
The entire renovation process described in the article took about four weeks from start to finish. This includes initial demolition, updates to plumbing and lighting, and addressing unexpected issues like old wiring and leaky pipes. The timeline also accounted for ordering materials and scheduling inspections, so you can expect a similar timeframe if your project has comparable work involved.
The article mentions checking for moisture or mold issues before starting. How did you actually perform that assessment, and if someone found a bigger problem than you did, would it be possible to stay within the original budget?
To assess moisture and mold, we visually inspected all surfaces for discoloration or musty odors and used a moisture meter to check behind walls and under flooring. If you discover a bigger problem, like structural rot or widespread mold, it may be tough to stay within your original budget. Addressing significant issues usually means allocating extra funds, but you can prioritize repairs and postpone some cosmetic updates to help manage costs.
How long did the entire renovation take from the day you started demolition to the final touches? I’m trying to figure out what kind of timeline to expect for a comparable bathroom size and scope.
The entire renovation, from the first day of demolition to the finishing touches, took just under six weeks. This included demolition, plumbing and electrical updates, tiling, fixture installation, and painting. For a similar bathroom size and project scope, you can generally expect a timeline of five to seven weeks, allowing for any unexpected delays or changes.
I’m in the early planning stages of my own bathroom remodel and noticed you mentioned addressing a minor leak at the toilet seal before demolition. Did you run into any surprises once you removed the toilet or start demo work? How did you handle them if so?
Once we removed the toilet and started demolition, we did find some unexpected water damage to the subfloor where the minor leak had persisted. To address this, we removed the affected section of subfloor, let everything dry thoroughly, and replaced it with new plywood before continuing. It’s a good idea to check carefully for soft spots or discoloration and be ready to do minor repairs like this during your remodel.
You mentioned discovering a minor leak at the toilet seal during the initial assessment. Were there any additional costs or complications with fixing that during the renovation, or was it fairly straightforward to address?
Fixing the minor toilet seal leak was fairly straightforward and didn’t add significant costs to the renovation. The team replaced the faulty wax ring while the toilet was removed for flooring updates, so labor overlapped with the planned work. No further complications came up, and the issue was resolved as part of the usual plumbing updates.
I noticed you mentioned checking for moisture and mold before starting demolition. Did you do all of the initial assessment yourself, or would you recommend hiring a professional for that part, especially if someone doesn’t have much renovation experience?
For our project, we did the initial moisture and mold checks ourselves because we had some renovation experience and access to basic tools like a moisture meter. However, if you’re not familiar with what to look for or aren’t comfortable with the process, it’s often safer to hire a professional. They can spot hidden issues you might miss, which can save you costly problems later on.
Could you share more about the permit process you went through for this project? I’m wondering if moving plumbing and electrical fixtures made permitting more complicated or delayed the renovation at all.
For this renovation, permits were definitely required, especially since we relocated plumbing and electrical fixtures. The process involved submitting detailed plans to the local building department and waiting for their review, which took about two weeks. Moving major systems like plumbing and electrical did add some complexity, mainly because inspections were needed at different stages. Overall, permitting added a few weeks to our timeline but ensured everything met code and was done safely.
I’m curious about the decision to switch from a fiberglass tub to a walk-in shower. Was there any structural reinforcement needed for the shower base, or did the existing subfloor suffice after fixing the minor leak?
In this renovation, after addressing the minor leak, the existing subfloor was carefully inspected for damage or weakness. Fortunately, the subfloor was still in good shape, so no major structural reinforcement was necessary. The contractor did add a waterproof membrane beneath the new shower base to ensure long-term durability and prevent future water issues, but the original subfloor was sufficient to support the walk-in shower.
For a similar 65-square-foot bathroom, how much flexibility did you have with moving plumbing and electrical fixtures within the original layout without going over budget?
In this renovation, we prioritized keeping major plumbing fixtures like the toilet and shower in their original locations to stay within budget, since moving them can increase costs significantly. We did have some flexibility to update electrical fixtures—relocating lights and adding outlets was manageable, as long as it didn’t require extensive rewiring. Small adjustments can be made, but major changes to plumbing or electrical usually require a larger budget.
I noticed you mentioned discovering a minor leak at the toilet seal during your initial assessment. How did you go about fixing that, and did addressing it add much to the overall renovation cost or timeline?
We fixed the minor leak at the toilet seal by replacing the old wax ring with a new one, which is a common solution for this kind of issue. The repair itself was straightforward and only added about an hour to the project timeline. In terms of cost, it was minimal—just the price of a wax ring and some labor, so it didn’t have a significant impact on the overall renovation budget.
