A small bathroom remodel typically costs $6,000 to $15,000, less than a full-size renovation but not proportionally less. Materials scale with the room; labor largely does not. A plumber charges much the same to move a drain in a 40 square foot bathroom as in a 100 square foot one, which is why small bathrooms look expensive per square foot.
How much does a small bathroom remodel cost?
Typically $6,000 to $15,000. If your bathroom is under about 40 square feet — a common size for a secondary or guest bathroom — this is the range that actually applies to you, rather than the larger figures you’ll see quoted for a full-size primary bathroom.
Materials cost less than a full-size bathroom, since there’s simply less tile, less flooring, and a smaller vanity to buy. But labor costs are broadly similar to a larger bathroom, so the total saving is smaller than the size difference alone would suggest.
Why does a small bathroom cost so much per square foot?
Labour does not shrink with the room. A plumber charges much the same to move a drain in a 40 square foot bathroom as in a 100 square foot one — plumbing, electrical, and tile setting all take similar time regardless of the room’s size, so that fixed labor cost gets spread over far fewer square feet.
This is the single most confusing part of small bathroom pricing, and it’s rarely explained clearly. A task like running a new supply line or setting a tile floor takes roughly the same number of hours whether the room is 40 square feet or 100 — the trade isn’t charging by area, they’re charging by time and complexity. That means the per-square-foot number for a small bathroom can look alarming even when the total project cost is genuinely lower than a larger bathroom’s.
What is the cheapest way to remodel a small bathroom?
Three specific decisions do more for the budget than anything else:
Keep the existing layout: avoiding plumbing relocation is the same principle that drives cost in any size bathroom, but it matters even more here — moving a drain costs close to the same whether the room is small or large, so that fixed cost is a bigger share of a smaller overall budget.
Reface rather than replace the vanity: keeping the existing cabinet box and replacing only the doors, drawer fronts, and hardware costs a fraction of a full vanity replacement, while still meaningfully changing how the room looks.
Use large-format tile: fewer individual pieces to set and fewer grout lines to fill means genuinely less labor time — in a small bathroom, where labor is already the dominant cost, this has an outsized effect on the total.
How long does a small bathroom remodel take?
Usually two to three weeks if the layout stays the same. Moving fixtures adds a week or more, plus permitting time.
Is it worth remodeling a small bathroom?
Yes, particularly if it is the only full bathroom or the main guest bathroom.
Dated bathrooms affect perceived home value out of proportion to their actual size — a small, outdated bathroom can make a whole home feel neglected in a way its square footage doesn’t really justify, which cuts the other way too: a small, well-finished bathroom can do a lot for how a home feels, for a comparatively modest budget.
Can I remodel a small bathroom for under $5,000?
Sometimes, with a cosmetic refresh — new fixtures, paint, a refinished vanity, and a new floor, with no plumbing changes.
Anything involving the plumbing takes the project above that figure, for the same labor-doesn’t-scale reason covered above. For the full picture on bathroom remodel costs generally, including what drives the biggest budget swings, see our bathroom remodel cost guide.
