here is the list

It depends on the remodeler. One that is licensed and will do a good job will most be around 10-12,000 to strip the bath to the studs and replace everything.

Costs will vary significantly based on where you live for labor and, even more, by the fixtures that you select. For example a faucet for a sink can be $100 or $1,000 + - same with light fixtures, sinks etc.

Other cost drivers are if you plan to move any plumbing, electrical and if the windows and walls will need to be removed and replaced.

If you do not move anything and just replace existing fixtures - expect to pay $1,000 to $2,000 for labor then add your fixture costs.

Depends, are you going to remove the tub? If so, you will have a considerable amount of tile to install.
Much of the expense will depend the on the materials you choose. Fancier means more expensive. Also, tile layout will change the price. If you want diagonal layout, it will cost more because of the extra cutting and time to measure and fit pieces where walls meet.

It depends on your budget. The sky is the limit really. Are you replacing or moving the shower/tub, stool and vanities? That is the most expensive part of a bath remodel. Flooring and lighting, mirrors and other accessories not so much unless you are going for the higher ticket items. We had a bath put into our basement in our previous home, kept it pretty low key (it’s a basement) and we still spent between $6000 & $7000. Get some quotes once you decide your budget.

Depends on what you’re looking for.

You can completely remodel for about 10K. If you choose fairly moderately priced items, you should be able to replace tile, vanities, sinks, faucets, countertop, toilet, and installing a new bath tub or shower stall. If you’re carefull you should have enough left over for a new shower enclosure (tempered glass door), towel bars, toilet paper holder, and vanity mirror or vanity cabinet.

Of course, if you do the work yourself you can save about $3500, maybe more depending on where you live.

For $15K, you could put in solid surface counters and boost up your faucets, vanities and tile by a notch.

depending on what you want in there around 6000$
