View Full Version : Cost to install Toto Guinevere unifit toilet

05-02-2010, 06:41 AM
We live in Phoenix and was wondering whats a fair price to pay a plumber to install a new flange and set a new Toto unifit toilet?

We have new tile being installed so the flange needs to be at a different height. Old flang is already out. (ABS pipe)

I could do it myself but when we picked it up yesterday I realized how heavy the new toilet is.

You can check my shopping cart and see what we charge.
It can vary depending on the City and State and local economy.
Also, not every business is the same.
When I was building homes, I wouldn't let the cheap guys touch my house.
There was too much at stake. I had one painting bid that was so low, that there was no way he was going to be allowed to touch all the raw woodwork and cabinets.
I would guess something like what I charge plus $50 on the flange, but then I'm not there.
The Guinevere is pretty heavy. About 110 pounds. For many, it's a two man job. My son and I were over 200.
Now I'm 176.5, so it will be interesting how much I will be able to lift when they let me.
I was told to not lift over 15 pounds for the first month or so.
I used to fling around 100 pounds.

Here are some pictures of a Guinevere installation. They are one of my favorite toilets. I like the Unifit adapter. If you ever need to pull the bowl and paint behind, you can lift up the bowl without disturbing the wax seal, paint, and then drop the bowl down again.


Make sure the contractor has 1/4" drill bits for masonry. We carry a small roto hammer with us.

Ready to drill the floor and set the Unifit with a wax seal.

hj lives in the Phoenix area, maybe you can give him a call. hj's page (http://www.terrylove.com/store/jacobson_plumbing.htm)

Hi Terry,

We're looking at getting the guinevere. A flooring installer (tile) says he knows how to install toilets as part of the job and that while they're in there, they'd just do it for us without any additional charges.. Do we need to consider getting an actual plumber instead? If so, do you know anyone in the L.A. area?

Also, I've been trying to figure out but haven't found a definite answer, as to what would be the minimum distance between the center of the bottom of the Guinevere toilet, and the most right part of the water supply inlet?

A good tile guy should be able to install the toilet. Not everyone is good. Toto toilets with the Unifit adapters require holes to be drilled in the floor. The instructions are pretty straightforward.

No offense to your flooring installer, but the Guinevere is not installed the same as most other toilets. It uses the Unifit Adapter and requires some additional work. You can look on the spec sheets found elsewhere in this site for the details on the minimum distance and water supply questions. You should make sure the flooring installer has the flange on top of the finished floor and not recessed below it.

The base at the floor looks to be 12", so if you have the supply at the floor, it may need to be about 8" to the left of center.
Higher up, the bowl narrows to 9.25", which means 5.5" to the left of center works if its coming from the wall at a normal height.
I just went and measured the Guinevere that I have.

Plenty of homeowners are installing the toilets with the Unifit.
It just takes a good 1/4" tile bit.

If the tile floor requires that the bowl needs shimming, then shim at the back before you tighten down the securing nuts.
That's always the method, shim first, so that the bowl is stable and without any rocking, then snug down the nuts.

I believe he did call, and I did give him a "sight unseen" estimate. It think he then decided to try to do it himself. Maybe like the guy who called last night. He must have been working on his broken main valve all day, because I doubt that he started a 8:00 p.m. I suppose he figured that since it was Sunday night on the Memorial Day weekend, a plumber was going to charge him at least $50.00, because he did not call back either.
