Bathroom Remodel Cost Calculator 2026

Estimate a 2026 bathroom-remodel planning range from bathroom floor area, remodel scope and a cost-market scenario before requesting comparable bids.

Bathroom remodel planning estimate

Price a bathroom from HomeGuide’s size table, using one installed rate per scope. This is a planning range, not a fixture list.

Nothing is saved. Floor area is the bathroom floor, not the whole house. Do not open a wet wall to measure the pipes.

Your planning estimate

Enter the bathroom floor area and a scope, then calculate.

How this estimate is calculated

Last pricing review: October 2026. Rates are fitted to HomeGuide’s size table, then rounded to the nearest $100.

1. Minor: $100 / $130 / $150 per sq. ft. Partial: $150 / $220 / $300 per sq. ft. Full: $250 / $350 / $500 per sq. ft. 2. Amount = floor area × that rate, in cents, with no other multiplier. 3. Multiply by 0.90, 1.00, or 1.15. Round to the cent, then to the nearest $100.

Check against the source table: 50 sq. ft. partial is $7,500–$15,000. Full at 35 sq. ft. is $250 × 35 = $8,750, which rounds to $8,800, beside the table’s $8,800 low end, and $500 × 35 = $17,500, the table’s high end. A 50 sq. ft. full job is $12,500–$25,000 before a scenario.

Before requesting quotes

Decide whether the toilet, sink, and shower stay in place. Put that in every bid.
Ask how the shower is waterproofed, and who warranties that layer.
Ask whether the fan vents outside, and whether the quote includes the fan.
Compare two or three scopes that name the same fixtures.

Safety

A bathroom remodel can open wiring and supply lines. This tool does not describe how to do that work. Waterproofing belongs in the contractor’s scope. A failed shower pan is a different repair from the remodel range above.

Questions homeowners ask

Does a bigger bathroom always cost more per square foot?: Not in this model. The rate stays the same across 15 to 200 square feet, which is how HomeGuide’s size table behaves. Very small rooms still have a toilet and a sink, so a real bid can beat the low end or miss it.
Is moving the shower included?: No. The source treats moved pipes and wiring as extra. They are listed under costs not fully captured, without a made-up dollar add-on.
Why is the 35-square-foot full low end $8,800, not $8,750?: Because $250 × 35 is $8,750, and the calculator rounds to the nearest $100. That lands on the same $8,800 HomeGuide prints for that cell.
Does this include a new bathtub?: A partial or full row assumes a broad fixture scope, not a named tub model. Ask the bidder to list the tub, valve, and glass.
