While it's true that a kitchen renovation brings the biggest dollar value back in sales price (depending on your market the exact amount it actually helps can vary), a bathroom remodel is important. I can tell you one thing, if you already have a tub in another bathroom, then I say the suggestion below about a walk in shower is a good one. If you are eliminating all the tubs, most of my clients from this year would have passed on the house. Yes that surprised me (especially since I am a showerer LOL) but it makes me think that a tub option should at least exist in the home. Also good for children too (tubs). However, if you already have one, then I say a renovation could be good. Here is my caveat. Call a real estate professional in your area before you remodel. That way you can see what a reasonable sale price would be for the remodel. I know that buyers are really looking for already done baths and kitchens. How MUCH you spend on a remodel or upgrade however, can vary. It might make more sense to go 'glam' or it might make more sense to just upgrade. A professional realtor can help with that info. Good luck!
