I don't know what you consider reasonably priced, but Newport Brass makes some nice, simple, high-quality wall-mounted faucets. I installed one of these in my master bath remodel this year:

Wall mount faucet

Whatever brand you get, remember two things:

1) Check the specs to make sure you have a high flow rate (at least 5-8 gpm) or your tub will take a long time to fill.

2) Make sure you have a long spout that reaches well over the tub edge: if the spout only barely reaches over the tub edge, you can have splashing outside of the tub if the water stream hits too high up on the inside of the slanted tub wall.

I've used Vigo when I needed a wall mount faucet. The threads are European, as long as your installer knows how to compensate for this....?

I was just looking at wall mount tub faucets for a freestanding tub this morning.

Haven't ordered from them yet, but Signature Hardware has lots of options that seem reasonably priced. Sales department was VERY helpful and knowledgeable when I called with questions. Lots of finish options and style ranging from very traditional to very modern.

One other thing to remember is to buy a recognized brand that will be around in 15 years when you may need to replace the cartridges. Nice-looking, but not-well-known brands, or European brands could be challenging if you need replacement parts. This is particularly important with a wall mount as replacement of the valve/ faucet typically involves opening up the wall. In my case, the faucet is mounted on a tile wall, so replacement would not be a fun project.

Signature Hardware isn't even certified to be sold in the US but somehow still hasn't been stopped.

Be VERY careful about wall mount anything with a freestanding tub. Tubs like that work best with floor mount fillers . You have to get the tub so close to the wall with a wall mount filler that there isn't room to clean. Or the spout isn't long enough, resulting in water outside the tub.

Thanks so much for the suggestions and advice. I am concerned about being able to get the tub close enough for a faucet reach but far away enough to clean.

Unfortunately, a floor mount is not ideal since we're on a concrete slab. A wall mount would be a much easier install. It would be on a wall backing up to the master closet, so I think we could also have a panel to access the plumbing.

I really like the Newport brass fixture, although it's a bit more modern than fixtures we've used in the other bathrooms. I would like to use a readily available brand name so parts are replaceable.

It won't be your least expensive brand but try Brizo by Delta. We went with the Charlotte for our claw foot tub and love the telephone style. There are a few other styles with wall mounts for tubs.

How long (in inches or cm) does the spout have to be at the very minimum?

Kudzu - you have a beautiful bathroom. Your wall mounted faucet looks like the same set up I would like to have except ours will be mounted along the back side of the tub, so we'll have access from the closet.

Do you have trouble cleaning around the base of the tub?

Cleaning around the tub is not a problem.

Beautiful selections. I tried to talk DD2 into that vanity, but it was a bit over her budget. Your bathrooms is lovely as well, kudzu.

I discovered Strom Plumbing when helping DD2 gut her MBath. She wanted the exposed shower set (Sunrise Specialty) but we went with Strom for the wall mounted tub filler. I think she purchased here, best price at the time. DH was leery, since he had never heard of the company, but the plumber said he had installed them before and thought they were a nice product. No trouble with any of her fixtures since her remodel in 2013.

Thanks so much for the link, Allison. I found a few that I really like and they're affordable too. I'll have to check the faucet extension length and the tub dimensions to see if one of these might work.

I plan on ordering this brand if/when we move. Glad I was able to help. Decorating forum slow this weekend, so I popped over to Baths.
