5×8 Bathroom Remodel Cost and Labor (2026 Baseline)

Illustrative selling prices at three markups, and the fully itemized direct job cost underneath it. Every quantity, rate, and formula shown.

Direct answer: A 5×8 bathroom (also written 8x5) with the tub replaced in place, a new tiled surround to the ceiling, new vanity and countertop, toilet, exhaust fan, lighting, wall and ceiling paint, and porcelain floor tile costs about $18,016 to $27,717, from a direct job cost of $13,858.38 in this example. Labor is $7,282.19 of that job cost, led by plumbing at $2,185.00. Direct job cost is labor and materials only, with no contractor overhead or profit, and is not a price: no contractor performs work at job cost. Rates are researched by three AI systems pricing the same stated scenario and reconciled by taking the median of their responses; no specific locality is selected and no statistically measured market median is claimed.

Modeled example in no specific locality is selected, and no statistically measured market median is claimed. Geographic basis: Clamp researched baseline rates, reconciled across three AI systems against a stated mid-market scenario; no specific locality and no measured market median.

Scope

  • Same-layout bathroom remodel
  • 60×30 tub replaced in place
  • 65 square feet of tiled tub surround to ceiling
  • New vanity with countertop and faucet
+ 5 more
  • New toilet
  • Exhaust fan replacement
  • Two light fixtures, five bath accessories and a mirror
  • Wall and ceiling paint
  • 28 square feet of porcelain floor tile in the open floor area

Assumptions

  • Existing floor joists and subfloor are structurally sound with no water damage
  • All rough plumbing and electrical connections remain in current locations
  • Wall framing and drywall behind tile are intact with no concealed rot or mold
  • Electrical circuits have adequate capacity for new fixtures without panel upgrade
+ 6 more
  • Standard 8-foot ceiling height and no concealed structural obstructions
  • Transcript did not specify a finish tier (basic/standard/premium); assumed standard given no descriptors of high-end or budget materials.
  • Attic or ceiling cavity access exists within 10 feet of fan location
  • Electrical circuit capacity exists for fan load without panel upgrade
  • Exterior wall or soffit is accessible for termination within 10 linear feet of fan
  • Ceiling framing is standard 16-inch on-center joists with no obstructions

Exclusions

  • Moving drain or supply line locations (rough plumbing stays where it is; the stub-outs are refreshed in place)
  • Electrical circuit additions or panel work (existing circuits reused)
  • Wall removal or layout changes
  • Subfloor replacement or structural framing repair
+ 9 more
  • Window or door replacement
  • Ceiling drywall repair or texture matching beyond 6-inch perimeter of fan opening
  • Attic insulation relocation or replacement disturbed during duct routing
  • Roof shingle removal or flashing work
  • Permit requirements vary by jurisdiction and must be confirmed locally.
  • Lighting work depends on the existing circuit and selected fixtures.
  • For homes built before 1978, follow applicable lead-safe renovation requirements before disturbing painted surfaces.
  • Fan duct or termination changes (the fan swaps onto the existing duct and roof termination).
  • Permit fees (Clamp's estimate carries them as a separate allowance with a range; not in these rows)

Cost summary job costs · no markup

This is not a price. These are job costs: labor and materials only. No contractor performs work at job cost. Overhead and profit go on top, and how much depends on what that contractor's business requires to operate.

Job costs only. These amounts estimate the direct cost to perform the work and do not include contractor overhead, owner compensation, or profit.

Illustrative contractor profiles, not recommended markups. Higher markup means more business behind the job. It does not by itself mean better work, and a lower markup does not by itself mean a better deal. Your correct markup depends on your actual overhead, sales volume, owner compensation, and profit goal.

Which price is closer to yours?

  • Lean, +30%: A handyman or owner-operator who does the work with a small crew and no office. Usually the lowest quote. The owner handles scheduling, questions and callbacks around the work itself.
  • Standard, +50%: A remodeling company with a crew, an office, insurance and someone to answer the phone. Close to the average remodeler's overhead in the National Association of Home Builders cost-of-doing-business survey.
  • Full-Service, +100%: A design-build firm with designers, a salesperson and a project manager who runs the job. The extra pays for planning, coordination and one point of contact from design to final inspection.

Higher markup means more business behind the job, not by itself better work, and a lower markup is not by itself a better deal. For contractors: how each markup splits into overhead and profit is in the overhead categories guide.

Labor cost by trade

Labor is $7,282 of the $13,858 direct job cost, or 52.5%. It is about 78 to 97 hours of work, including setup, daily cleanup and material runs. That is what the labor costs the contractor. In a quote, markup goes on every job cost dollar, labor included, so the labor inside the price is the labor cost times the markup multiplier.

Labor priced at what a remodeler pays a trade sub for the work (the sub's price carries its own burden, overhead and profit), with no overhead or profit of the remodeler's own. Hours are person-hours at typical production from Clamp's labor hours catalog, as a range: a planning figure, not a schedule. Setup, daily cleanup and material runs are about 15% on top of the line hours; a sub's price already covers its own. Multipliers are the same illustrative profiles as the cost summary, not recommended markups. Each trade's line items are in the itemized table.

Every row links its assembly version and rate source in the published data; quantities show net measures with stated waste. Hours are person-hours at typical production, on labor rows only, and the direct-cost row adds about 15% for setup, daily cleanup and material runs; an allowance or material row names the labor line that installs it, and a subcontract row has none, because the sub's price includes their own time.

Persona names are illustrative labels, not measured pricing practices. Illustrations apply markup to direct cost only and are not recommended markups. Direct job cost is what the work costs a contractor to perform, not a price: no contractor performs work at job cost, because overhead and profit are what keep the business running. Higher markup means more business behind the job. It does not by itself mean better work, and a lower markup does not by itself mean a better deal.

Same scope, different jobsite: condition modifiers

These modifiers apply to labor only. $6,576.19 of materials, allowances and other non-labor cost is unchanged in every row, so the direct cost moves by less than the labor factor suggests. One condition applies at a time against the baseline; conditions do not combine.

Questions

How much is labor for a 5x8 bathroom remodel?

In this snapshot, labor costs the contractor $7,282, or 52.5% of the $13,858 direct job cost. Tile is the largest share at $2,185, then tile at $1,241 and demolition and prep at $1,164. Marked up at the illustrative profiles, the labor inside a quote runs from $9,467 at 1.30x to $14,564 at 2.00x.

Is an 8x5 bathroom the same as a 5x8?

Yes. Both describe a 40 square foot bathroom, the common size with a 60 inch tub along the 5 foot wall. This page prices that room with the tub replaced in place.

Why is labor marked up too, not just materials?

Markup covers overhead and profit for the whole job, so it applies to every job cost dollar. Leaving labor at cost would mean the hours you run the job pay nothing toward the business behind it.

What does replacing just the shower cost?

Replacing only a 3x5 (60x36) shower has a direct job cost of $4,765 to $9,037 in Clamp's published example, from an acrylic base with a surround kit to tile walls on a mud-bed pan. All five builds are itemized in 3×5 shower replacement cost.
