Yes, I believe it is. We really like the tub. I was kind of surprised at how long the water stays hot. I've used the tub a few times and I leave the water in to see how long it stays warm, it's been at least an hour since it was filled and it would still be warm enough to be in. We did have them stuff additional insulation around the tub before closing in the walls as I was concerned because our last tub did not retain heat. I also didn't think I liked the style where there is handles down the side as opposed to the more oval tub, but after I've used it, I realized how functional those are - my arms just sit right in them when using the tub, which is very nice, and you can steady yourself as you're getting out without getting water over the edge of the tub. I agree, I think we need a window sill because i can imagine it will get sticky. He said it was a potential mold issue but I don't see how as long as we're running the fan when using the shower/tub.

Krissie, I highly recommend Matt Oliver at Oliver Custom Homes in North Austin. We just finished building a house with him and he is incredible. He also does a lot of remodels. We couldn't have been happier. His number is 845-0208. I'll be happy to answer any questions you might have about him. Trudy Here is a link that might be useful: Oliver Custom Homes

Start by looking for general contractors in your area, it's not likely you are going to find one person that goes from plumbing to tile to carpet to hardwood floors plus the associated carpentry work. Get references and go check them out. In your area it shouldn't be hard to get five or six estimates and then narrow it down. Ask for at least three references from each gc and check out all of them.

+1 on handymac - lumberyards would carry 1 3/4" x 7" for a 2x4 wall and 1 3/4" x 9' for 2x6 walls and they are most generally made of Ponderosa Pine.
