I've used both Redguard and Hydroban, with good results. As with all things - 'there is not one best'.

If you like TEC, then why not go with their waterproofing.

I tend to think that Laticrete's Hydroban is the gold standard.

Either product will work. They key is to prepare the surfaces, cracks, coves and edges correctly and then apply the coating correctly.

Both products are fine. I do think Laticrete (Hydroban) has some of the best customer and warranty support out there.

If someone offered me a choice of the two, I'd choose Hydroban.

FYI I went with Hydroban in my shower and Nobelseal TS on the bathroom floor

Thank you everyone! I think I will go with the Hydroban! :) Although I love the TEC products for thin set and grout, it looks like the Hydroban is pretty popular among tile contractors.

Hydroban is really simple to apply and dries to a nice olive green color. You can fill gaps up to 1/8" with Hydroban, but when I did my shower I made sure the tilers used tape and thinset to fill any gaps before they applied two coats of Hydroban....paying particular attention to the floor/wall and curb/wall junctions.

Is Hydrobarrier better than Hydroban? Thank you Tundra Finish Works LLC!

All good advice here. Nice to see such consistent, positive help. Post some photos when you're complete. Forever baths are wonderful. Not to throw a knot into your plan, but any chance you're going curbless?

We are not going curbless...I know it is better for disability reasons in the long term, but I don't like the look personally and I like to contain the water!

A properly designed curbless shower DOES contain the water! The important part is "properly designed". The best waterproofing that exists can be all for nothing if the shower underneath it is improperly built. That goes for curbed or curbless. Be sure the pre-slope is correct, and correct for the materials chosen. Be sure the interface with the drain is correct, and no weep holes are blocked. Be sure the curb is built correctly, and detailed correctly.

The details Behind the waterproofing are just as important as the waterproofing. And the framing behind those details is included in those things that not enough people pay attention to, until it is too late, and they have a wavy tile installation because the walls were framed poorly. You won't be using any contrasting grout with wavy walls!

My mother's house had curbs on the showers. She was fine until the last couple of years because she had parkinson's. One step over the curb was about as hard as you or I trying to climb up to the top of the Empire State Building.

My shower is on the third floor of my house......a curb on the shower is the least of the accessibility issues.

After much thought, we have decided to go curbless. We might not ever needed it, but there is a good possibility we will welcome our aging parents into our basement area if they ever need it. It is a walkout that we can easily make handicap accessible and we have the space to add a small kitchen. We haven't yet installed the curb on the shower (it is on a slab), so our plumber thinks it is a good idea. Thank you everyone!
