Estimated project range
$7,500 – $14,000
This range assumes professionally-installed, permitted work by a reputable remodeler. Actual quotes swing based on existing plumbing, subfloor condition, and each contractor's overhead. Use it to plan and to sanity-check quotes. Don't confuse it with one.
How this calculator works
Every input maps to a published data anchor. Base ranges by scope and shower type come from 2024 HomeGuide and Angi national bathroom remodel data. Regional multipliers come from the RSMeans City Cost Index. Finish tier multipliers come from Remodeling magazine's Cost vs. Value Report.
Add-ons use conservative labor and material midpoints (curbless entry: roughly $3,500 for a subfloor drop-in and linear drain; frameless glass: about $3,000 more than framed; subfloor repair: around $2,200 for a 20 sq ft joist and subfloor patch).
Why the range is so wide
Bathroom remodel quotes for the exact same room routinely land 2 to 3 times apart. Two reasons. First, contractors scope different work: one bids the shower swap, another bids the shower plus vent fan plus subfloor plus new lighting. Second, hidden conditions show up during demo (rotted subfloor, out-of-code wiring, cast-iron drains) and those trigger real change orders.
The calculator's high number assumes moderate change-order exposure. If your home is under 10 years old and on a slab, expect the low end. If it's over 40 years old with a basement below, budget the high end and treat any leftover as bonus contingency.
Frequently asked questions
How accurate is this calculator?+
It's a planning tool, not a quote. Your actual bids should land within the range about 80% of the time. The 20% outliers are usually either lowballs that missed scope items, or high-end custom builds with imported materials.
Why does the range change so much when I switch regions?+
Labor is the single biggest cost driver in a bathroom remodel. West Coast and Northeast labor rates run 20 to 30% above Southeast and Midwest rates, so the same scope produces meaningfully different totals.
Should I trust the low end or the high end when budgeting?+
Budget the high end. Most remodels finish 10 to 20% over the original quote thanks to change orders, so anchoring to the top of the range absorbs typical surprises without wrecking your finances.
