Bathroom Remodel Cost Calculator

Bathroom remodels run roughly $70 to $350+ per square foot, depending on scope and finish. A surface refresh is about $70–$120/sq ft, replacing fixtures in the same layout $120–$200, a full gut $200–$300, and a remodel that moves plumbing or changes the layout $300–$400+. Because bathrooms are small and packed with plumbing, tile, and fixtures, they carry one of the highest per-square-foot costs of any room. A typical 50–60 sq ft full-gut remodel at mid-range quality lands around $12,000–$18,000. Enter your size, scope, quality tier, and upgrades in the calculator to anchor the estimate.

A small bathroom (around 30–50 sq ft, like a guest or hall bath) typically costs $5,000–$15,000 depending on scope and finishes. A cosmetic refresh might be $3,000–$6,000, while a full gut with new tile, fixtures, and a vanity runs $8,000–$15,000. Counterintuitively, small bathrooms cost more per square foot than large ones, because the same fixtures (toilet, vanity, shower/tub), plumbing, and tile work get concentrated into a tiny footprint — the fixed costs don't shrink with the room. Keeping the existing layout and choosing mid-range finishes are the best ways to control a small-bathroom budget.

Bathrooms pack an enormous amount of work into a small space. Within a few square feet you have plumbing (supply and drain lines for a sink, toilet, and tub/shower), electrical (lighting, outlets, exhaust fan, sometimes heated floors), waterproofing, tile, cabinetry, and multiple fixtures — each needing skilled trades. That density of plumbing, electrical, tile, and finish work, plus the waterproofing critical in a wet space, drives the per-square-foot cost far above a bedroom or living room. The labor of multiple trades coordinating in a tight area is the main reason bathrooms (and kitchens) are the priciest rooms to remodel.

A surface refresh keeps the layout and structure and updates visible surfaces — paint, a new vanity and mirror, updated fixtures and hardware, maybe new flooring. It's the cheapest and fastest. Replacing fixtures swaps the tub, vanity, toilet, and finishes while keeping them in the same spots. A full gut strips the bathroom to the studs and subfloor, then rebuilds with new waterproofing, plumbing, tile, and fixtures — letting you fix hidden problems and fully modernize. A layout change does all of that plus moves plumbing fixtures and possibly walls, the most expensive option because rerouting supply and drain lines adds significant plumbing labor and often opens walls and floors. The calculator's scope selector covers all four.

Yes — relocating the toilet, shower, or sink is one of the most expensive changes in a bathroom remodel. Moving fixtures means rerouting both supply and drain/vent lines, which often requires opening walls and the floor, and drain lines in particular need proper slope and venting, sometimes involving the floor structure below. That adds plumbing labor, possible structural and permit work, and time. Keeping fixtures in their existing locations is one of the best ways to control cost. If the current layout works, a 'replace in place' remodel delivers a fresh bathroom for far less than a layout change. In the calculator, this shows up both as the 'layout change' scope and as a 'relocate/new plumbing' upgrade.

The finish tier is the biggest single swing in a bathroom budget because the room is fixture- and tile-heavy. Builder-grade/budget finishes (stock vanity, basic tile, standard fixtures) run about 30% below the mid-range baseline. Mid-range — quality tile, a nice vanity, name-brand fixtures — is the most popular and the baseline. High-end/designer (custom tile, premium fixtures, stone tops) adds about 40%. Luxury (imported stone, custom everything, high-end glass and fittings) can nearly double the base. Since the same scope can cost wildly different amounts depending on materials, the quality tier is one of the first decisions to make. The calculator multiplies the scope rate by your chosen tier.

A typical full bathroom remodel takes about 2–4 weeks, though the bathroom is usually only fully out of service for part of that. A cosmetic refresh may take just a few days. A full gut-and-replace with new tile, fixtures, and a vanity runs 2–3 weeks. Projects that move plumbing, change the layout, or use custom tile and materials take 4–6 weeks or more. Timelines also depend on permit approvals and material lead times — custom vanities, special-order tile, and glass shower enclosures can add weeks. Tile work has built-in waiting too: waterproofing and thinset must cure before grouting and use. The calculator estimates cost; your contractor sets the schedule once the scope is set.

The highest-return updates are usually mid-range, broadly appealing improvements rather than ultra-luxury features. A clean, modern vanity and countertop, updated lighting and a quality mirror, fresh tile (especially a well-done shower or tub surround), a new toilet, and good ventilation deliver strong returns and appeal to most buyers. Walk-in showers are increasingly desired. Quality fixtures and timeless finishes age better than trendy choices. Over-improving for the neighborhood — luxury finishes that exceed comparable homes — yields diminishing returns. A mid-range bathroom remodel typically recoups roughly 60–70% of its cost at resale while making the home more sellable.

Keep the existing layout so you don't pay to move plumbing — that's the single biggest saver. Choose mid-range fixtures and tile that look great without luxury prices, and limit tile to high-impact areas (the shower and floor) rather than every wall. Reglaze or keep a sound tub instead of replacing it, and keep cabinetry that's in good shape. Shop in-stock vanities, tile, and fixtures to avoid custom lead times and markups. Do your own demolition or painting if you're handy. Finally, get multiple detailed quotes, lock the scope before demolition to avoid costly change orders, and keep a 10–15% contingency for surprises behind the walls.

For a like-for-like surface refresh (paint, swapping a vanity or toilet in place), often no. But once you change plumbing or electrical, move fixtures, alter walls, or do a full gut, most jurisdictions require permits and inspections — for the plumbing rough-in, electrical, and sometimes framing. Permits ensure proper waterproofing, venting, GFCI protection, and code-compliant work, and unpermitted bathroom work can cause insurance and resale problems (inspectors and buyers flag it). A licensed contractor typically pulls the permits and schedules inspections as part of the job. If your remodel touches plumbing or electrical — which most full remodels do — budget for permits.
