My guest bathroom looked like it was frozen in 1987. Beige tile. A vanity with fake wood grain. A toilet that ran constantly. I had $1,000 to fix it. No contractor. No prior tile experience. Just a weekend and a lot of YouTube.
Here is exactly what I did, what I spent, and the three mistakes that almost wrecked the project.
Where the Money Actually Went – The Full $950 Breakdown
Most people assume a bathroom renovation costs five figures. That is true if you move plumbing or buy a $2,000 freestanding tub. This was a cosmetic-only refresh. No moving walls, no new toilet flange, no electrical work. Just the surfaces and fixtures you touch every day.
| Item | Cost | Notes |
|---|---|---|
| Vanity (RTA – ready to assemble) | $210 | IKEA GODMORGON knockoff from Home Depot. 30-inch, solid wood doors. |
| Vanity top with sink | $85 | Glacier Bay white cultured marble. Fits standard 30-inch cabinet. |
| Faucet | $55 | Delta Lahara. Not the cheapest, but Delta has lifetime warranty on cartridges. |
| Toilet | $120 | American Standard Cadet 3. Flushes clean. No more running. |
| Paint + primer (1 gallon) | $45 | Behr Marquee in semi-gloss. Mold-resistant formula. |
| Grout + caulk | $30 | Custom Building Products sanded grout + GE Silicone II caulk. |
| New mirror | $40 | IKEA STORJORM. Simple, beveled edges. |
| Light fixture | $60 | Globe Electric 3-light vanity bar. Matte black. |
| New towel bar + toilet paper holder | $35 | Delta Trinsic. Brushed nickel, matches faucet. |
| Shelving + accessories | $50 | Floating shelf from Target, bamboo toothbrush holder, soap dispenser. |
| Tools + consumables | $120 | Grout float, sponge, putty knife, drop cloths, painter’s tape, new supply lines. |
| Total | $950 |
I saved $50 by not buying a new toilet seat. The Cadet 3 comes with a decent one. I also reused the existing drain pipe and stop valves. Both were in good shape. If yours are corroded, budget another $30 for brass replacements.
The Two Jobs That Look Hard but Are Actually Easy
Replacing a Vanity Without Moving Plumbing
You do not need a plumber for this. Measure your current vanity width. Standard sizes are 24, 30, 36, and 48 inches. If you match the width, the supply lines and drain will line up within an inch or two. Flexible supply lines handle the rest.
Steps: Shut off water. Disconnect supply lines. Unscrew the drain P-trap. Pull the old vanity. Patch the wall holes with spackle. Slide the new one in. Connect everything back. Tighten by hand plus a quarter turn. Done in three hours.
Painting Over Old Tile – Yes, It Works
I did not replace the shower tile. It was structurally fine, just ugly beige. I used Rust-Oleum Tub & Tile Refinishing Kit ($35). Cleaned the tile with TSP. Sanded lightly. Applied two coats with a foam roller. It looks like new white subway tile from five feet away. Up close you can see roller texture, but it is a guest bath. Good enough.
One warning: this paint takes 72 hours to fully cure. Do not use the shower for three days. I ignored this. The paint peeled in one corner. Had to sand and re-coat. Follow the cure time.
Three Mistakes I Made So You Don’t Have To
Mistake 1: Forgetting to measure the rough-in for the toilet. The rough-in is the distance from the wall to the center of the toilet flange. Standard is 12 inches. Mine was 11.5. The Cadet 3 fits 12-inch rough-ins perfectly, but I had to cut 0.5 inch off the drywall behind the tank. Barely noticeable, but annoying. Measure before you buy.
Mistake 2: Using cheap caulk. I bought a $3 tube of white caulk. It cracked within a month. Spend the extra $5 on GE Silicone II. It stays flexible and does not mold. Do not cheap out here. Water damage behind caulk is how bathrooms rot.
Mistake 3: Not ordering the vanity top at the same time as the cabinet. The vanity top took two weeks to arrive. The cabinet was in stock. I had a cabinet sitting in my living room for 14 days. Order everything together. Check lead times before you start.
When You Should NOT Try This – The Hard Truth
This budget works for cosmetic renovations only. If any of these apply, call a pro:
- Water damage in subfloor or drywall. If the floor feels spongy or you see black mold, you have rot. That is a thousand-dollar repair by itself.
- Moving plumbing. Relocating a toilet or shower drain requires cutting concrete or joists. Permit required. Plumber required. Budget $2,000 minimum.
- Electrical work beyond swapping a fixture. Adding outlets, moving switches, or running new wire? Hire an electrician. A $50 mistake can burn your house down.
- You hate DIY. If the thought of cutting drywall makes you anxious, this project will make you miserable. Save up $3,000 and hire a handyman for the labor. You buy materials, they install. Still cheaper than a full contractor.
The Best Tool I Bought for $15
An oscillating multi-tool. Specifically the Chicago Electric from Harbor Freight. It is $15. It cuts drywall, PVC pipe, caulk, old grout, and nails. I used it to trim the vanity backer board, cut the old caulk line, and notch the drywall for the toilet. Worth every penny. A Dremel or DeWalt version costs $100+. The cheap one works fine for one project.
Final Verdict – Can You Really Do This?
Yes. But only if you keep it cosmetic, measure everything twice, and accept that it will not look like a $10,000 renovation. The toilet flushes silently. The vanity does not wobble. The paint on the tile has held for six months with no peeling. I spent $950 and three weekends. For a guest bathroom that guests actually use, that is a win.
If you have a small bathroom with good bones and bad finishes, this plan works. Skip the contractor. Buy the oscillating tool. Measure the rough-in. You will be fine.
