must have a very smooth bathtub bottom
592312
Liked the mat. Hated trying to get it out of the package and took a while to lay flat. My bathtub isn't perfectly smooth so didn't work for me. I put it up on my tile wall to see if it would stick and it stayed up for nearly 2 weeks until I got my lazy self to take it down. Gave it away to someone with a smoother bathtub bottom. I thought it was just ok but didn't hate it.

The white coating in the tub was not done evenly. You can see the blue through the inside of the tub.

Beautiful tub. Some finish problems at the edges, caulk is going to be a bit thick there, but not a big deal. Difficult to level.

Will only stay stuck to very flat/slick surfaces. Like the material of the bathtub. We have flat tile in our kids shower, but it's not a slick surface and will not stay put. It is always falling.

This is a BIG pyramid and may not fit so well in aquariums smaller than 3 gallons. Like most aquarium decor it has a rough surface but looks pretty realistic overall. The one thing I disliked was the extremely sharp edges around the inside bottom which made it tricky to clean.

You really do need to push down most of the buttons for it to stick to the bottom of the tub, but if you don't mind that, it is otherwise perfect.  My kids think it's fun to push down the buttons anyway.

Have not tried them yet.  Like most new tubs, mine is textured, but still not safe.  I am experimenting with various mats and will then try these since most products do not work well in textured bottom tubs.

I bought two packs and they covered the bottom of the bathtub perfectly.
I didn't want to fall in the shower due to "lack of adhesive ducks". Great buy.

This is an attractive tub, but the tile flange along the top edge of this tub is thicher than I've ever seen before.  Installation instructions specify that cement board should be shimmed out 1/4" all the way around the tub.  If you shim out the left and right tub wall, to do it correctly, you must continue to ship out those walls as they extend out into the bathroom.  The contractor certainly wasn't happy about that, but I insisted that the bathtub be installed per the manufacturers installation instructions.  My contractor said that he would not recommend purchasing that tub again because of the extra work it required.

This product is exactly as described and is very solid. I took off one star because it does not work well on all bathtubs. It works on my tub because I have a standalone bathtub. However I let my daughter borrow it upstairs and it did not fit well. Make sure your tub has ledges at the same height, directly across from each other, and at least a few inches of space. Also be aware of the tub spout being in the way.

I have a textured surface on the bottom of my tub.  It still gets slippery with soap on the bottom.  Especially if I use my foot exfoliator/pumice stone.  I am a senior citizen and not as stable on my feet as I used to be.  After a couple of near falls I decided it was time to put some sort of anti skid decals on the bottom of my tub.  These adhered very well.  But they are virtually the same surface as my tub.  I haven't taken a shower yet but tried them in a dry tub with no water.  They are no less slippery than the tub surface.  If they get less slippery when I shower I will update this but I am already thinking I will have to replace them with something else.

Now that I have used them, they definitely do what they are supposed to do.  They work well.

if you follow the directions, it makes an attractive edging around the tub.  You need to be sure to really clean the surfaces before installing.

I wish they would make something like this to work in a textured tub. I got it thinking I could make it work somehow but I wasn't able to. I love the idea of it, but since a lot of tubs are textured these days, I would think they would come up with a way to make it work. I had to send it back. On the positive side, the seller refunded all of my money.

love the tub.  american std americast is lighter version.  i like to offset the faucet so two can bathe more easily in the 5.5 foot tub.  takes 4 men to carry to install

The quality is OK, but I wish it had a smoother bottom.  I may have to add some little felt pads to the bottom of the canister.  Otherwise I'm afraid it might scratch my quartz countertop.

This is a nice looking deep bathtub. I am using it for 2 months now and there are quite a few cons that I wish I knew before buying it.
1- To drain the water, you need to press the drain hole at the bottom of the bath. So if the kids forget to leave out the water, I need to dig in & get wet all the way up past my elbow to press the drain to release. Most baths have the option somewhere near the top of the tub. This is so frustrating.
2- Because the drain hole is located at the bottom it gets pressed down accidentally many times while in the bath. Especially when the kids are bathing, and they find themselves without water in the tub!
3-This has an indentation on the side of the tub which is supposedly made to keep your arms. It is too small to hold your arms, and it just makes the bath narrower.
