Heading into 2027, most full remodels of a 5 × 8 bathroom cost about $11,900 to $16,100, while a cosmetic refresh can come in under $11,000 and a gut remodel can pass $20,000.

5 × 8 bathroom remodel cost at a glance
These ranges use national average prices for a 40-square-foot full bathroom. They include demolition, plumbing and electrical rough-in, drywall and paint, fixtures, a new exhaust fan, and permits.
| Project | Typical cost |
|---|---|
| Refresh (same layout, swap finishes) | $8,400 – $11,400 |
| Full remodel (new everything, same layout) | $11,900 – $16,100 |
| Gut and redesign (one fixture moved) | $17,500 – $23,700 |
| Budget full remodel | $10,200 – $13,800 |
| Full remodel with tiled walk-in shower | $16,000 – $21,600 |
| High-end with tiled shower, quartz, and new lighting | $25,800 – $34,900 |
That works out to about $250 to $520 per square foot. Location matters too: the same full remodel runs about $14,900 – $20,200 in California and about $10,500 – $14,200 in Alabama. The calculator adjusts for your state.
Where the money goes in a 5 × 8 remodel
Here’s how a typical midrange full remodel of a 5 × 8 bathroom breaks down, with a new tub/shower combo, ceramic tile floor, stock vanity with a cultured marble top, and a standard toilet:
| Cost category | Typical cost |
|---|---|
| Labor, prep, demolition, and permits | $5,600 – $7,600 |
| Tub and shower | $2,400 – $3,200 |
| Flooring | $400 – $550 |
| Vanity and countertop | $1,300 – $1,700 |
| Toilet, faucets, mirror, and lighting | $1,750 – $2,350 |
| Exhaust fan | $500 – $700 |
Labor is the largest single cost in a small bathroom, usually 40% to 65% of the total. That’s why the size of the room matters less than the scope of the work: a bigger floor adds a little tile, but moving a toilet or building a tiled shower adds thousands.
5 × 8 bathroom layout and what it means for cost
Most 5 × 8 bathrooms put the tub or shower across the 5-foot back wall, with the toilet and vanity side by side along one 8-foot wall. That layout is efficient and inexpensive to keep, because the drain, supply lines, and vent are already in place.
- Keep the tub, or convert to a shower. A tub/shower combo is the cheapest option. Swapping the tub for a tiled walk-in shower raises a full remodel to about $16,000 to $21,600.
- Pick a 30- to 36-inch vanity. That leaves enough clearance in front of the toilet, which most codes require to be at least 21 inches.
- Consider a pocket or outswing door if the door swing hits the vanity or toilet.
- Use light colors, a large mirror, and clear glass to make the room feel bigger without moving walls.
What changes the price
- Scope: Keeping the layout is the biggest money-saver. Moving a toilet, sink, or shower adds about $2,500 per fixture.
- Shower or tub: A tub/shower combo with a surround costs about $2,800 installed. A tiled walk-in shower with glass costs about $7,500, and more with high-end finishes.
- Tile: Tiling walls outside the shower adds roughly $25 per square foot at midrange. Use our tile calculator to estimate how much you need.
- Vanity and countertop: A stock vanity with a cultured marble top is about $1,500 installed, while semi-custom cabinets and quartz cost more. See our countertop cost calculator.
- Hidden problems: Rot under an old tub, outdated wiring, or a fan that vents into the attic can add several hundred to a few thousand dollars.
Ways to save
- Keep the tub, toilet, and sink where they are.
- Choose a tub/shower combo or a prefab shower instead of a custom tiled shower.
- Tile the floor and shower, and paint the other walls with moisture-resistant paint.
- Do the demolition and painting yourself if you’re comfortable with it.
- Buy a stock vanity and spend a little more on the faucet and shower valve you use every day.
- Get three written quotes that list materials, labor, permits, and cleanup.
