A 5×7 bathroom is 35 square feet and is one of the most common hall-bath footprints in U.S. homes. In 2026, a practical planning range is about $3,000 to $20,000+ depending on scope. A straightforward full remodel that keeps the existing layout often lands around $7,500 to $15,000, while premium tile, plumbing moves, or major water damage can push the total higher.

Why a Small Bathroom Can Still Be Expensive
The room is small, but it still needs the same core trades as a larger bathroom: plumbing, electrical, waterproofing, tile, carpentry, ventilation, and finish work. Fixed mobilization and permit costs are spread across fewer square feet, so small bathrooms often cost more per square foot than larger rooms.
5×7 vs. 5×8 Bathroom Cost
A 5×7 bathroom has 35 sq ft versus 40 sq ft for a 5×8. Material quantities change slightly, but the biggest cost categories—tub or shower, toilet, vanity, plumbing, electrical, waterproofing, and labor—are nearly the same. Compare our 5×8 bathroom remodel cost guide and 5×10 bathroom remodel guide for larger footprints.
Example Midrange Budget
For a 5×7 bathroom with a new tub or shower surround, standard porcelain tile, a stock vanity, a new toilet, updated lighting, fresh paint, and no layout changes, a planning budget around $9,000 to $13,000 is reasonable in many markets.
Biggest Cost Drivers
- Plumbing relocation: Moving the toilet, tub drain, or vanity supply lines can add substantial labor.
- Custom tile: Small-format mosaics and complex patterns take longer to install.
- Waterproofing: A tiled shower needs a complete waterproofing system, not just decorative tile.
- Hidden damage: Rot, mold, soft subfloor, and leaking plumbing are common surprise costs.
- Ventilation and electrical: Fan upgrades, GFCI protection, lighting, or outdated wiring can expand the scope.
Keep the Layout to Control Cost
The easiest way to keep a 5×7 project under control is to leave the toilet, vanity, and tub or shower where they are. Once drains and supply lines move, the contractor may need to open walls or floors and coordinate more plumbing, electrical, drywall, and tile work.
Contingency for Older Bathrooms
Bathrooms hide moisture damage better than most rooms. A contingency of roughly 10% to 20% is useful when the space is older or has a history of leaks. If demolition reveals a sound subfloor and framing, that reserve stays available for upgrades or remains unspent.
Decisions That Matter Most in a 5×7 Layout
A 35 sq ft bathroom has very little spare space, so a few layout decisions can change the scope quickly:
- Tub or shower: keeping the existing bathing footprint usually limits demolition compared with rebuilding the wet area.
- Vanity: changing width or plumbing location can affect wall repair, flooring, supply lines, and storage.
- Toilet location: moving it is a much larger scope decision than simply replacing the fixture.
- Tile coverage: a tub surround, full-height shower, floor, and decorative walls all create different tile-labor quantities.
- Ventilation and electrical: fan, lighting, switches, receptacles, and any outdated wiring should be identified before finishes are closed up.
For a small bathroom, keeping the basic fixture locations is often more important to the budget than saving a few dollars per square foot on tile.
A Simple Quote-Comparison Checklist
Ask every contractor to show whether demolition, disposal, waterproofing, plumbing, electrical, tile setting, fixtures, paint, permits, cleanup, and hidden-damage allowances are included. If two totals are far apart, the scope sheet usually explains why faster than comparing the headline price.
FAQ
How much does a typical 5×7 bathroom remodel cost?
Many full remodels fall around $7,500 to $15,000, but a cosmetic update can be lower and a premium full-gut project can exceed $20,000.
Can I remodel a 5×7 bathroom for $5,000?
It is possible with a limited scope, existing layout, budget fixtures, and little hidden repair work. A complete gut remodel is less likely to fit that budget.
What should I spend money on first?
Prioritize waterproofing, plumbing, ventilation, and sound installation before decorative upgrades. Failures behind tile are much more expensive to repair later.
