The honest answer is that a bathroom is priced by what is behind the wall, not by the square footage. Two rooms the same size can be twenty thousand dollars apart, and it usually comes down to three things: whether the plumbing moves, what the shower is made of, and what nobody found until demo day.
Moving plumbing is the big lever
Leaving the toilet, sink and drain where they are keeps a remodel dramatically cheaper. The moment a drain moves, you are cutting concrete slab in most East Valley homes, and that is a different job with a different number. It is often worth it. It is never cheap, and anyone quoting it casually has not thought about it.
A tile shower is not a shower pan
A prefabricated insert goes in fast. A custom tile shower is framing, sloping, a full waterproofing system, tile, grout and glass, and it takes a skilled tile setter days rather than hours. It also lasts decades if it is built right and fails inside five years if it is not.
Build in a contingency for what is behind the drywall
Older East Valley homes hide things. Corroded supply lines, a vent that was never right, framing that was cut for a pipe run twenty years ago. We tell homeowners the day we find it, price it in writing, and get approval before we touch it. Set aside something for it in your own budget too.
What to ask for in a quote
Ask for an itemised scope rather than a single number. You want labour, materials, permits and finishes separated so you can see where the money sits and what happens if you change a tile selection. If a quote is one line, you cannot compare it to anything.
Financing spreads a lot of this out. Plenty of our clients run a bathroom in the region of $250 a month rather than paying up front, and we will walk you through what that looks like at the estimate.
