Tom isn't a fan of windows in a shower because, as he puts it, "you have exterior conditions--rain and heat--on the interior." But in the case of the first- and second-floor bathrooms he had no choice; there was no room to move the openings and no budget for new windows set higher up on the wall. Removing them and closing up the walls would have cost $800 per window. So he created all-weather protection for the existing wood sash by painting them with exterior latex paint and using waterproof PVC, which costs the same as wood but won't rot, for the window trim.
What They Saved: $1,600
