Here's a video of Kerdi-Line linear drain, it's the one I'm getting for my 2'x2' tile shower. They recessed the shower pan area but no joist cutting or floor raising is required. This has been out over a decade and is tried and tested IF installed properly it will last the life of the home. Things to consider though. With the entry linear drain option you really should water proof all the walls out a few feet past the shower as well as the entire bathroom floor. With the linear drain on the far wall from the entrance on a LARGE shower area (mines 5' by 5') you need to recess the shower pan 2 inches ore more which means cutting the joists or raising the bathroom floor 1 inch or more. For a small shower it's perfect and is the best option in my opinion for an unbroken large tile look. Linear drains under the controls are awkward for the tile guy so he needs to be good. I've seen repairs made on linear curbless failures so the install needs to be done right (no air bubbles in thin sets and continuous water proofing installed correctly with no kinks or air pockets.

When you are dealing with a slab, you have to know what pans you want and how the drain configuration is done - otherwise - they will simply block out the shower area and not pour anything - which is an option - then they can set the pan when it's selected and plumb accordingly. All they need to have is a rough idea on what end it's going to drain and put in a trap, etc. The linear drains I have see are really just linear "on the top" and they they slope and drain under the grate / cover into a center or offset round drain hole - so they are not all that different than a regular drain - other than the placement on the edge vs the middle.

Thank you all for your input! I told my mom about the watering and the shade and she said she'll do it. Karen, the rose is new. We got it this year. But it grew like crazy and was blooming in no time. My mom was actually a little surprised. The TZ was growing and blooming better than some of our older roses. My apologies for the pictures. I'm not the best photographer. As for the soil drying out in between waterings, I wasn't quite as clear as I should've been. I typed this post after several hours of mind-numbing calculus homework (I'm not the best at math). Anyways, they don't wait for it to be 100% dry before watering again. My apologies for not being clear about that. I think I might go back and edit my original post to fix that. They water them in the early evening. We have a lot of mosquitos because of a retention pond that's really close to our house so my parents try to get out and water them before Our roses were fine last summer so that's why we're a little perplexed. Only the TZ is unhappy. All of our roses get the same amount of sun and the same watering schedule but four out of five are doing great. Two of them seem like they might have gone dormant or something like that but they still look happy and healthy. Is the TZ a more...sensitive kind of rose? I don't know if that's necessarily the right word, but it's the only one that I can come up with at the moment. Thanks again for the help. I really appreciate it!

From personal experience, having a linear drain installed and having been used to center drains before that: center drain is a whole lot less to maintain, especially with a good drain cover (small holes) to prevent hair going in drain, no cleaning of the drain area itself needed besides the cover. no clogs either if hair doesn't really get into the drain. residue builds up in the linear drain that needs periodic cleaning, some scrubbing will generally do, but caked on grime may require Tilex/bleach/baking soda/hydrogen peroxide to help clean. Some red mold also can build up, again scrubbing and Tilex/bleach will take care of it. fully/truly cleaning the strainer hair catcher basket in terms of squeaky clean requires a lot of work, easy if u just want to remove hair and minor gunk off the basket. Truly cleaning basket squeaky clean requires methods like strubbing with brush and soaking in hydrogen peroxide to get the remaining grime to come off and have it looking like "new" again. With center drain, never had to deal with this cleaning mess. no clogs or no clogs for quite some time if hair catcher basket cleaned regularly, if it overfills, or maybe over time even with cleaning/hair removal, some hair still slips through into drain, so you may have to de-clog drain from rare time to time. So far in 2 years, I only had to de-clog the drain once for a partial slow draining clog, it might have been related to forgetting to clean hair catcher basket for some time once because of my knee injury - either that or some hair slips through from time to time to eventually have the slow draining clog. aside from a real drain clog in the drain pipe, linear drain won't clog in terms of drainage if the hair catcher has hair in it unless it is full of a lot of hair. Surprisingly, it still drains pretty well with quite some hair in it. We generally clean out the hair catcher like every 2 days to every week. Also wanted to mention with center drains, today, there are also infinity drains that mount as center drains, it's a recessed square area above the drain pipe, below your tiles, optionally with a hair catcher basket in some designs. The linear drain is just one type of infinity drain. I don't think I've seen a center infinity drain that's circular, it's always square center drain recessed design. I wouldn't recommend this (center infinity drain) either based on my experience with linear drain, as I suspect it is also a pain to maintain compared to a traditional center drain with just a drain cover.
