Planning for height specifics in the powder room

Just to remind you, since it's been awhile since I shared my powder bathroom plans, this is the look that I was going for. As you can see, I wanted to install a wall-mount sink faucet over tile or black shiplap. 

Step 1 for this project was to get the flooring in, because the flooring affects the height of where to place the faucet. So, we got the flooring in!

After the flooring was installed, we picked the vanity out, ordered the sink and countertop and ordered the faucet parts (more on this later in this post). The next step of the renovation was to figure out the height for the wall faucet.

How do you place wall mount bathroom faucets?

1. Have your flooring in place. This gives you a starting point for your measurements.
2. Have your vanity and sink picked out and, if possible, available in the space to visually make sure you like what you are going with.
3. Decide on your faucet spout (straight or with a downward curve). Have the faucet in the space to help determine height of faucet on the wall.
4. Hold the faucet up to the wall to see what visually looks good as well as what will be functional for washing your hands. 

For my faucet and an under-mount sink,  9" above the vanity was a really good place to wall-mount the faucet.

The faucet and parts that I ordered were all Kohler because they had the longest spout available. Here are the exact parts that I ordered, in case you are interested. 

My husband and I did the measurements and then called in our plumber to tackle the rest... and that's where we ran into major problems. So,...

Is a wall mounted bathroom faucet expensive to install?

Yes! They are more expensive than a traditional sink faucet to install and are also more expensive to buy. The issues with a wall-mount faucet is that they have to have the piping and sink drain in the right spot. If they aren't in the right spot, then they have to be moved.

If you are installing a wall faucet, expect to face some issues when you open up the drywall to expose the plumbing. You won't know what the issues are though, until you cut the drywall to see behind it. 

For us, this is where we ran into major problems. Our house is a split-level with four half floors. Directly above the powder bathroom is the main bathroom. So, our plumbing (hot and cold water lines and drain) in the powder bathroom are running up to supply the main bathroom as well. To reconfigure the lines and the drain, we would have to take off the majority of the bathroom wall and the ceiling. 

Taking off the ceiling runs into another issue because we have asbestos in our popcorn ceiling. I shared all about asbestos abatement and cost a few years ago, but if you aren't familiar with it... it's expensive. 

Our plumber said that because of how the lines were ran and because the master is directly above, a floor joist would probably have to be cut as well. At this point, the quote went from about $200 (to install the wall mount sink faucet by itself) to about $3k (rerunning the pipes, asbestos abatement and redoing all the drywall). 

At this point, I was on the fence to be honest. I really love the look of a wall-mount bathroom faucet BUT that cost is pretty high; especially since you don't really know exactly what's above the ceiling until you get to it. 

Another thing that factored in to this was..

How do you repair a wall mount bathroom faucet if there is an issue?

To repair a leak with a bathroom wall faucet, you have to get behind the wall. Since we were tiling the wall, we'd probably not ever notice a leak unless we put a sensor in or the leak was bad enough to show on the floor or something. When my plumber told me this over the phone before I knew about the whole plumbing line issue, I wasn't that concerned. We were hiring a professional and had bought quality plumbing parts, so I was ok with taking the risk. 

BUT, ultimately, after discovering the issues with our plumbing lines and combining that with the thought of what it would take to repair the faucet if it leaked, I think we decided it would be in our best interest to get a typical sink faucet. 

I love the look but $3k just to have the look of a faucet overhanging my sink doesn't make much sense to me. We ultimately ended up with a great look even without a wall mounted sink faucet.
