I've done 2 minor bath re-habs in the past 5 years.
One turned out great (that was the second one)
1st was a disaster from the start. Irresponsible contractor.
Suggestions, if you don't already have a walk-in shower, get one. Spend the $$ for tile, not one of those fiberglass jobs. A bench in the shower is nice. Wouldn't hurt to have grab bars installed. You might not need them now but that time will come (I know!)
Elevated toilet, quality vanity & sink, heated floor if possible.
One of mine has wood wainscotting, I saved a lot of $$ doing the finish work on that myself 2 coats of a sealer before it was installed and on all the other wood trim.
Jetted tubs are nice, if you use them, otherwise a waste.
My 2 cents worth....
