How to Estimate a Bathroom Remodel | Reddit & LinkedIn

A clean bathroom remodel estimate has seven groups: demo, plumbing and electrical rough-in, waterproofing, tile, fixtures, vanity and finish carpentry, and a contingency. Keeping them separate matters because a client will change their mind on selections, and you want each change to move one visible number instead of forcing a full rebuild.

Tile and labor are usually the two largest lines on a mid-range bath, often 45 to 60% of the total. Price tile and the waterproofing membrane from live supplier quotes. Fixtures are frequently a client allowance rather than something you supply. Labor is where your experience shows, so break it into demo, rough-in, set, tile, and finish stages instead of one lump.

Split labor into demo, plumbing and electrical rough-in, waterproofing and tile, fixture set, and finish work. Assign hours to each stage and multiply by your loaded labor rate, the rate that already covers wages, taxes, insurance, and overhead. A small bath with a tiled shower can run 60 to 90 labor hours once tile detail is included.

Stage-based labor gives you two advantages. It makes the estimate credible to a client who can see the work is thought through, and it maps directly onto payment milestones, so a rough-in draw lines up with the labor you have actually completed. Guessing one lump labor number is how contractors lose a weekend of margin on a single job.

Bathrooms hide the most expensive surprises: rotted subfloor under an old shower pan, mold behind tile, galvanized supply lines, or a drain that is not where you expected. Price the waterproofing system as its own line so it is never the thing you cut to win the bid, because a callback on a leaking shower erases the profit on the whole job.

Name a contingency of 8 to 15% for what you cannot see until demo. Write into the estimate that conditions discovered behind finished surfaces bill as a change order. Unused contingency can be credited back, which keeps the client relationship clean and makes the next bid easier to win.

Bathroom remodels commonly run 18 to 26% markup depending on your market and risk. Apply markup to materials and subcontracted work, and make sure your labor rate is already loaded so you are not marking up a number that is missing overhead. The goal is a net margin you can live on after a job that ties up a crew for one to three weeks.

Contingency on a bathroom is often higher than on a kitchen, 8 to 15%, because so much is hidden behind tile and old plumbing. A named contingency is honest with the client and keeps one surprise from wiping out your profit. State clearly how any unused portion is handled so there is no dispute at final invoice.

ContractShield builds the estimate from photos in about 25 minutes. Snap the bathroom, say or type the scope, and the AI drafts labor and materials from your own price templates, line by line for you to approve. Every line shows whether the price came from your template or an AI estimate, and it never invents your labor rate or markup.

Once the client signs, the same tool invoices the milestones through Stripe, sends automatic reminders, and runs Collections on anything past due. You keep your pricing and your margin, and you stop losing evenings to spreadsheet math. Cost is a flat 2% per job, 1% client and 1% contractor, capped at $250 per job, with no per-lead fees ever.
