Quick answer
A 5×10 bathroom remodel cost averages $18,706 for a full remodel with demolition and about $11,582 for a cosmetic remodel without it, for bathrooms of 40 to 150 square feet, according to This Old House’s bathroom remodel cost guide.
A 5×10 bathroom is 50 square feet, and for that size the same guide’s tiers run $8,478 to $10,883 for a basic refresh, $14,609 to $19,040 for a midrange update, and $27,492 to $35,808 for high-end work.

5×10 Bathroom Remodel Cost by Scope
These 5×10 bathroom remodel cost figures come from national cost data. The size bands tell a similar story: a 40 to 60 square foot bathroom runs $12,695 to $14,845, which sits between the basic and midrange tiers, and a bathroom of 130 square feet or more runs $22,370 to $24,715. The tiers and the size bands don’t line up neatly, so ask a contractor which scope its price follows.
| Scope | Typical range |
| Basic refresh, 50 sq ft (paint, hardware, lighting) | $8,478 to $10,883 |
| Midrange, 50 sq ft (updated vanity, flooring, fixtures) | $14,609 to $19,040 |
| High-end, 50 sq ft (premium materials, custom cabinetry) | $27,492 to $35,808 |
| Full remodel with demolition, 40 to 150 sq ft (average) | $18,706 |
| Cosmetic remodel, no demolition (rough figure) | $11,582 |
| Average primary bathroom remodel | $15,586 (range $6,456 to $24,715) |
Because scope changes a 5×10 bathroom remodel cost more than square footage does, use the table as a starting point and not a quote. A new layout, moved drains, or a custom shower can push a 50-square-foot room well past the midrange figure.
Why the Published Figures Disagree
The guides don’t agree on a small bathroom. Block’s bathroom cost guide puts a mid-range remodel of a bathroom under 50 square feet at $6,000 to $15,000, while This Old House’s midrange tier for a 50-square-foot room is $14,609 to $19,040. The two bands barely overlap, so the gap is a question of scope. Ask each contractor which work its number includes.
The same gap shows up in the broader averages. Block puts a full mid-range remodel at $15,000 to $30,000, with a national average near $16,500. Its guide also notes that the same 50-square-foot footprint can cost $8,000 or $80,000, depending on what changes inside the walls.
Where a 5×10 Bathroom Budget Goes
A small bathroom has fewer materials to buy, but it carries much of the same fixed work as a large one. Old fixtures still have to come out, lines still have to be rerouted or capped, and the trades still run in sequence. Because that work is spread across fewer surfaces, a 50-square-foot room rarely comes in at a proportionally lower price than a larger one.
- Demolition and disposal. Removing tile, the vanity, and the fixtures is separate labor, and hauling it away is a separate line.
- Fixtures. Confirm which items the quote supplies, such as the toilet, vanity, faucet, mirror, and lighting, and which it only installs.
- Plumbing changes. Moving a fixture changes the scope and needs a licensed plumber.
- Ventilation and electrical. A new fan, outlet, or light circuit adds work that a cosmetic quote often leaves out.
- Tile and waterproofing. Floors and shower walls need a membrane and proper sealing. Ask for waterproofing as its own line.
- Finish work. Paint, trim, caulking, and cleanup are easy to overlook in a first estimate.
Component Costs for Line-Item Checks
Published averages for individual components help you check each line of a 5×10 bathroom remodel cost estimate, though each figure may cover a different scope:
- Complete shower remodel: $8,044, including materials and labor.
- Plumbing for a bathroom renovation: $5,545 on average. About two-thirds of remodels include plumbing work.
- Cabinetry: $2,929 to install, including removal of the existing cabinets.
- Tiling: $1,326. Painting: $1,145. Flooring: $1,114.
- Toilet: $467 for the unit and installation. Countertop installation: $332.
Demolition and What It Adds
The full-remodel average includes demolition and disposal, and the cosmetic average does not. That gap is the first thing to check when you compare 5×10 bathroom remodel cost quotes. If one contractor’s total is lower, confirm whether it removed the old fixtures and tile or left that work out.
Plumbing Changes and Permits
Miami-Dade’s permit guidance exempts replacing a sink, toilet, or faucet when a licensed plumbing contractor does the work, and plumbing repairs by a licensed contractor up to $500 in materials and labor. Relocating or reconfiguring plumbing, ventilation, or electrical work needs a building permit. Moving a tub drain or a supply line falls in that second group, so ask the contractor who pulls the permit and what its fee covers.
Block’s guide puts the cost of relocating a single fixture, such as a toilet, sink, or shower, at $1,000 to $5,000. Permits run $100 to $1,000, and separate plumbing and electrical permits add up.
Labor and Trade Rates
Block’s 2026 figures put plumbers at $85 to $175 per hour and electricians at $60 to $145 per hour, with coastal urban markets at the top of the plumbing range. Ask whether each quote assumes a licensed trade for the plumbing and electrical lines, since the permit exemption above depends on it.
Hidden Costs and Contingency
About one in three homeowners spend more than they expected on a bathroom remodel, and nearly one in four run into unexpected water damage. Around 22% find structural repairs they did not plan for.
Plan a contingency of about 20% of your 5×10 bathroom remodel cost before the walls open, since hidden water damage and structural repairs are the usual causes of overruns. Block’s guide suggests 10% to 20% of the total project budget, which on a $25,000 bathroom is $2,500 to $5,000.
Budget Benchmarks
Experts recommend spending 5% to 10% of your home’s value on a bathroom renovation, according to This Old House’s bathroom cost guide. On a $200,000 home, that is $10,000 to $20,000. The midrange 5×10 bathroom remodel cost sits inside that band, which makes it a useful sanity check rather than a target.
Cosmetic or Full Remodel
A cosmetic remodel suits a bathroom whose layout and plumbing already work. It replaces the vanity, fixtures, lighting, and surfaces without opening the walls. A full remodel makes sense when the footprint changes, the shower moves, the drain is relocated, or the subfloor shows water damage. Decide the scope before you compare bids, because the two options differ by several thousand dollars in a small room.
The guides also disagree on cosmetic work. This Old House puts a cosmetic remodel without demolition at about $11,582, while Block puts a cosmetic refresh of paint, fixture swaps, vanity replacement, and lighting at $5,000 to $10,000 with no layout change and no tile replacement.
Questions to Ask Before You Accept a Quote
- Does the price include demolition and hauling away the old fixtures?
- Is any plumbing relocation priced separately?
- Is waterproofing for the shower area itemized?
- Are the fixtures supplied by you or by the contractor, and is their installation priced?
- Is the ventilation fan replaced, and is that in the quote?
- Who pulls the permit, and what does its fee cover?
