Pick the scope first
With a small hall or guest bath, the question is how much of the room you are replacing. There are three common scopes.
| Scope | Price | Days |
|---|---|---|
| Refresh: vanity, top, faucet, mirror, floor tile, lighting, fan, paint | $4,500–$12,000 | 2–4 |
| Refresh plus the tub replaced by a shower | Add $7,900–$16,500 | 3–5 more |
| Full remodel: everything out, everything new | From $18,500 | 10–15 |
Why small does not mean half price
A 40-square-foot bathroom has the same number of fixtures as one twice its size: one toilet, one vanity, one tub or shower, one fan. The plumber and electrician do nearly the same work either way. Demo, haul-away, waterproofing and the permit do not shrink much either.
What does shrink is tile. Less floor and less wall means fewer boxes and fewer labor hours. That is why small bathrooms usually land near the bottom of each range, not far below it.
Layouts that make a small bathroom work
In a small bathroom the layout decides more than the finishes do. These are the moves that usually make the biggest difference:
- One fixed glass panel instead of a swinging shower door, so nothing opens into the room.
- A low curb or curbless entry where the slab allows it, which lets the floor tile run through and makes the room look larger.
- A floating vanity that shows more floor, with a drawer instead of a deep cabinet.
- A recessed medicine cabinet or a shower niche instead of shelves that stick out.
- A pocket door when the door swing hits the vanity or the toilet.
- Larger tiles with fewer grout lines, and light both above the mirror and in the shower.
None of these need the plumbing to move, which is where small bathrooms often stay affordable. Moving the toilet or the drain is the change that adds the most to the price.
Where small bathrooms save money
- Keep the layout. In a small room there is rarely a better place for the toilet anyway. Leaving drains where they are avoids cutting the slab.
- Stock vanity sizes. A 30- or 36-inch stock vanity with a quartz top costs far less than custom and fits most hall baths.
- Fixed glass panel. A single panel with no door costs less than an enclosure and makes the room feel bigger.
- One tile, used well. The same large-format porcelain on the floor and shower walls cuts waste and grout lines.
Where small bathrooms cost extra
Tight rooms are slower to work in. One trade fits at a time, and materials get staged outside the room. If the bathroom is the only one in the house, the schedule has to keep a working toilet as many nights as possible, which can add a day.
Older Phoenix, Tempe and Mesa homes with original hall baths can also hide old supply lines or a leaking tub drain. We look for signs at the in-home visit and the contract spells out how hidden conditions are handled.
