In most cases, removing a tub and installing a well-appointed walk-in shower does increase the value of a home. Removing your only tub to install a walk-in shower can make your home's value take a hit because most prospective homebuyers, especially families with small kids, want at least one bathtub so if you plan on installing a walk-in shower and you want the most value for your home, ensure that there is still at least one tub in the home.
