Free Bathroom Remodel Estimate Template & Generator
Most of what a bathroom estimate prices gets buried. This one takes a 42 square foot hall bath from an alcove tub to a tiled shower and puts the hidden work on its own lines: the sloped bed and bonded membrane, the flood test before any tile is set, 129 square feet of tile split into labor and an owner-selected allowance, the fan duct, and unit rates for the subfloor rot the walkthrough already suspects.

Use-case checklist
What to include in a bathroom remodel estimate
Waterproofing is the line customers most want to cut and the one that cannot be redone later. If the membrane is thin at the curb or the pan never gets flood tested, nothing shows up for a year or two, and then it shows up as a stain on the ceiling below and a demolition bill for tile that was installed correctly on top of an assembly that was not. Nobody pays for that twice except you. Pricing the assembly as its own line, with the test written into it, makes it something the homeowner approves rather than something they never knew happened. Concealed damage is the second trap. A soft spot at the toilet flange almost never stops at the flange, so a subfloor rate per square foot and a plate rate per linear foot, agreed before demolition starts, keep day three from turning into a renegotiation.

Worked example
A 42 sq ft hall bath converted from alcove tub to tiled shower
Keystone Bath Works is pricing the hall bathroom at 26 Fenwick Avenue for the Adeyemi family, walked April 9, 2026. The room is 5 ft 4 in by 7 ft 10 in, the alcove tub and fiberglass surround come out for a tiled shower, and the floor already feels soft at the toilet flange.

When this document is the right choice
Use this estimate to set a realistic expected cost before the final scope is known. An estimate is an informed approximation, not a final invoice. State the assumptions that could move the price and replace it with a quote or invoice once scope is confirmed.
Frequently asked questions
How should the flood test appear on the estimate, and when does it happen?
Give it a place in the sequence, not just a mention. The test happens after the pan and membrane are complete and before any tile goes down, and it holds the schedule for roughly a day. Put that hold on the estimate so the homeowner understands why nothing appears to be happening, and photograph the filled pan with the water line visible. That photograph is the only evidence the assembly was tested once tile covers it, and it is worth more than any sentence you write.
This is the only full bathroom in the house. What does the estimate have to say about that?
Put the days on the page, because the homeowner is pricing a hotel or a relative's spare room alongside your figure and will not raise it until demolition has already started. State the working days from demolition to a usable shower, and mark which of those days are holds rather than work, since a house with nobody in it looks like a crew that stopped caring. Then say what is available in between: whether the toilet gets reset temporarily at the end of a phase, whether the household is down to a half bath, and whether you are on site consecutive days or waiting on an inspector you do not schedule. Say what a concealed damage find does to the finish date too, because that is the one thing that moves it, and the homeowner should hear it here rather than on day three.
Why can the shower glass not be ordered at the same time as everything else?
Because it is measured off the finished tile, not off the drawing. Walls are never perfectly plumb, tile adds thickness that varies with the setting bed, and a frameless panel cut to a drawing dimension will not fit the opening you actually build. Write the glass as an allowance measured and ordered after tile is set, and put the fabrication lead time on the schedule, because the gap between a finished tile shower and a usable one is the part homeowners are least prepared for.
The homeowner asks for a niche and a bench after the estimate is accepted. Why are those not small additions?
Because each one is a hole you then have to make waterproof. A niche is framing, a sloped sill, a bonded return wrapped on every face, and cut tile on five surfaces. A bench is a structure standing inside the shower with the same membrane carried over it and a slope that has to shed water toward the drain. Neither is absorbed by a per square foot tile rate, and both are exactly where a shower leaks when they get added in a hurry. Price them as named lines with dimensions and a tile detail, and settle them before the walls close, because the framing has to be in before anything is waterproofed. If the homeowner wants to keep the option open, carry the framing now and the finish as an allowance, which costs far less than opening a finished wall.
What do I say about the exhaust fan and where it vents?
Price the duct run, not just the fan, and say where it terminates. Venting into an attic or a soffit cavity instead of to the outside is a moisture problem that surfaces later as stained sheathing, so state the termination point, the duct size, and whether the run is insulated, as the example does with a 6 inch insulated duct to the exterior soffit. Fan sizing and duct requirements are set by your local code, so confirm what applies with your building department before you commit to a number.
