I see no problem with getting what you want...go for it! I don't think what you are talking about is so radical it will compromise the bathroom. It's true that some couples will prefer a bathroom with two sinks, but some will prefer a bathroom with a bath tub. How long would the vanity be if you shortened it?

Could you move into the guest room? Remove the panels on that tub?

Your project sounds like it will be expensive and devalue your house. Most couples today want two sinks and maximum closet space.

Thank you for your comments.

Do what is comfortable and easy for you. Would you be comfortable moving into the guest room and just removing the glass enclosure? If that would be a comfortable and easy solution, it could save you some money and wear and tear, with workers in and out, etc. As far as resale value, I would not worry about that so much. One thing I have learned in my 5 plus years here on Houzz is that people love to tear up perfectly good spaces. So do what works for you and let the next buyer tear it up if they don't like it - because chances are they are going to tear it up anyway.

I think you just have to weigh whether for the next 5 yrs or so that going through the expense and remodel is worth the pleasure knowing that taking a sink and part of a closet more than likely will hurt the resale of your home. Unless there are other strong selling points ( like being on water) that a buyer could look past these short comings. Another way to look at it, in 5 yrs who knows what the real estate market will look like. Right now, anything is pretty much selling. And in 5 yrs it could be the opposite or not. At least you know for the next 5 yrs, you would enjoy your tub which is the only known factor.

After many years of home ownership, I realized that the home I live in is for me. Otherwise it reminds me of when I was growing up and people would place clear plastic covers on their sofas - that you stuck to in the summer - because they were more concerned about what things looked like than being comfortable in their homes.

Thanks latifolia! You've just convinced me that I don't need to spend all that money on a tub when I can use the one in my guest bath. Hurts me to give up the idea, but it doesn't make good financial sense.

It’s generally easy to remove the doors and switch to a shower curtain. If you will only use it as a bath, you won’t even need that. And depending on the present tub, you may want to change it to a deeper soaking tub. It will still be your private space!
