I have finished major part of the project, still need to fix small things like paint work on the wooden boarder, arbor over waterfall, rails, aquatic plants and fish. here are some pics; Mia, thanks again for the pump and filters, it is working great, lift lot of water. Thank you all for all those tips to make it happen. Here is a link that might be useful: Hot Bath Tub Water Garden

I have had a bathtub spout with the handheld shower above it. You can also simply replace a regular shower head with the hand held which has the flexible jointed metal water hose (or what ever they are called). The big box stores carry them. Since you don't have a shower over head, you can only get a deck mount, which I also had. It sat next to the roman tub spout and the metal hose sat behind the false front. As an alternative, go to Wal-Mart and buy the blue & white scrubber on the extendable handle for reaching the far sides of the tub. They also sell replacement heads. Sold by the mops? I use this in my roman tub. Works great, easy, cheap.

Yes, the plumbing needs to be done first. Yes, you may be able to just get another acrylic shower wall to cover over everything, if the wall is not moldy or wet behind the tile that you are looking at. There is no need to replace the tub itself if it is in good shape, even if you do decide to take down the wall tile and replace everything from the studs out. Just make sure the workers cover the tub well to protect it while the work is being done. I am with Monicakm_gw, get some more bids for the work. You might want to have them bid on just replacing the walls with new fiberglass, and on doing the whole new tile job, too. You can see new walls at Lowes, Home Depot, and Menard's online. There is also the whole Marbleite wall option to look into. Local dealers for Marbelite are supposed to be cheaper than buying from big box stores, if I remember right. While you are fixing plumbing, you should probably put in a proper mixing valve to protect from scalds. It is the code now. No one will be able to turn the water too hot to burn themselves and flushing the toilet or using the water elsewhere in the house will not burn the person in the shower anymore, either. I have read the experts here on the forum say that the Symmons Temptrol system is very good and is a good value. Here is one that comes with the shower head and tub spout for under $100. http://www.homedepot.com/p/Symmons-Temptrol-1-Handle-Tub-and-Shower-Faucet-in-Chrome-S-96-2/100643619

I’m not sure where your leak is coming from, I just wanted to tell our experience so you can gauge whether it might be a possibility in your case. One of our guest bathrooms had a leak that we originally assumed was from the shower. We hadn’t lived in the house for very long, and we hadn’t even used that shower yet when my sister came to visit. She stepped out of the shower and realized that water was squeezing up between the tiles when she stepped on them. Naturally, she informed us. My hubby had the entire bathroom completely gutted in half an hour! (It was a small bathroom with a Fiberglass shower, the tiles popped up like toast out of a toaster, and he’s just a beast... lol!) we see evidence of long term damage and provide my sister with another bathroom to use for the remainder of the visit. We didn’t start the bathroom remodel immediately, and when we did start it was slow going. We were very fortunate because we had barely started the remodel when we got another weather front move in with a whole lot of moisture... (It has been snowing a lot during her visit) and that’s when we realized the bathroom was leaking from another source! Hubby again ripped up the bathroom, and this time ripped out part of the wall that is on the exterior and that’s when we realized the leak was coming from outside. It took us a bit to figure out but we finally determined (with outside help) that it was because that wall was directly against an exterior chimney that had not been flashed properly. We left that bathroom unfinished for quite a while while we fixed the chimney problem, and waited for some more really good rain storms to make sure it was indeed dry before we finished our bathroom remodel. We were just fortunate that we have a lot of other bathrooms and this was just a guest bathroom. Anyways, I hope your issue isn’t something like that!
