Loan Bathroom Remodel Estimator
Bathroom quotes arrive as a single scary number with no anatomy. This estimator builds yours the way contractors do — a per-square-foot base by finish tier, plus the fixture upgrades itemised — and shows it as the range it honestly is.
Fixture add-ons are scaled by tier (×0.75 budget, ×1.0 mid, ×1.6 premium) because the same "new shower" is a fiberglass kit at budget and a tiled, glass-doored build at premium. Per-sq-ft bases follow 2026 national cost-guide planning figures.
How it works
Base cost = size × tier rate: $85 budget, $175 mid-range, $350 premium per sq ft, the planning bands published in 2026 national cost guides for full bathroom remodels. Fixture add-ons are mid-priced reference points (tub/shower refit $2,500, double vanity $1,200, heated floor $1,500, tile-shower conversion $3,800) scaled by the tier factor, because fixtures are where tiers actually diverge. The final range is the computed midpoint ±20% — the honest spread for permitting, plumbing surprises behind walls, and regional labour.
Method & worked example
Method: Midpoint = size × tier rate ($85 budget / $175 mid / $350 premium per sq ft) + fixture add-ons scaled by tier (×0.75 / ×1.0 / ×1.6): tub-shower refit $2,500, double vanity $1,200, heated floor $1,500, tile-shower conversion $3,800. Range = midpoint ±20%.
Worked example: A 50 sq ft mid-range bathroom with a tub/shower refit: base $8,750 + $2,500 = $11,250 midpoint, range $9,000–$13,500. A 35 sq ft budget refresh with no add-ons: $2,975 midpoint, range $2,380–$3,570.
When to use this
- Planning a bathroom remodel and needing a defensible budget number before quotes.
- Choosing between a budget refresh and a mid-range gut of the same room.
- Deciding which fixture upgrades survive the budget — priced individually here.
- Checking a contractor's number against national per-sq-ft planning figures.
How to use it, step by step
- Measure the bathroom's floor area.
- Choose the tier that matches your actual fixture and tile intentions, not your hopes.
- Toggle the fixture upgrades you are genuinely including.
- Read the range — and budget to the midpoint plus your own contingency.
- Get quotes; the ones far outside the range owe you an explanation.
What the inputs mean
| Input | What it is | Typical values |
|---|---|---|
| Size | Floor area of the bathroom | Powder 15–25, full 40–60, primary 100+ sq ft |
| Tier | Finish level setting the per-sq-ft rate | Budget $85, mid $175, premium $350 |
| Fixture toggles | Itemised upgrades, tier-scaled | Tub refit, vanity, heated floor, tile shower |
Another worked example
A small hall bath, 35 sq ft, budget tier, no fixture upgrades: base $2,975, range $2,380–$3,570. That is the refresh-and-replace-in-place job — same layout, same plumbing points, new surfaces and fixtures — and it is the remodel most likely to come in at or under its midpoint.
Frequently asked questions
How much does a mid-range bathroom remodel cost?
At 50 sq ft and $175 per sq ft the base is $8,750; add a tub/shower refit and the midpoint is $11,250, in an honest range of $9,000–$13,500. That matches what national cost guides report for a mid-range bathroom in 2026.
Why does size matter less than tier?
A 35 sq ft budget refresh estimates at $2,975; the same room at premium tier with a tile-shower conversion and heated floor passes $20,000. Fixtures, tile and glass — the tier choices — swing the budget five-fold while size barely doubles it.
What is the most expensive fixture upgrade?
The tub-to-tile-shower conversion at $3,800 mid-tier ($6,080 at the premium scaling) — it is plumbing, waterproofing, tile and glass in one line. Heated floors feel luxurious but price lower, at $1,500 mid-tier.
Does a bathroom remodel pay back at resale?
Mid-range bathroom remodels have historically recouped roughly 60–75% of cost at resale in national cost-vs-value reporting — among the better rooms for payback, though never a guaranteed return. Premium remodels recoup less in percentage terms.
How can I cut the cost without cutting corners?
Keep the layout (moving the toilet and shower drains is the expensive sentence in any quote), refresh at budget tier, and spend the savings on the one fixture you touch every day. Layout changes can add 20–30% before a single finish is chosen.
🍳 And the kitchen?
The Kitchen Remodel Estimator runs the same tier math on the most expensive room in the house — with the cabinet and countertop shares broken out.
What's the difference between a remodel and a renovation in a bathroom?
Trade usage: a remodel changes fixtures, finishes and sometimes layout within the room; a renovation can include structural repair, moving walls and new plumbing runs. Quotes use the words loosely — the tier and fixture inputs here describe the work, whatever it is called.
How long does a bathroom remodel take?
A mid-range, same-layout bathroom runs 2–4 weeks of working days once materials are on site. The tile shower conversion adds the most calendar time (waterproofing and cure windows), which is part of why it is the priciest add-on.
