acrylic showers have thier place if you can live with it, it will be cheapest route. they do atleast dry out between showers, can be easily serviced. the only downfall of them is the wasted/lost space. In a average 32 acrylic the actual room inside is more like 28 1/2" and thats anywhere there is no shelf or handle, you loose another 9 inches in each corner, thats where they need the most support (for shipping) I am continuously asked about this question by my clients. Here is my opinion and why. I suggest the use of a poured cultured marble pan. we do the others but this is why. I do not like the way that the drain attaches to the liners in a wet-bed, I have been called back to 3 showers in the last 5 years where they have began to leak. none of the 3 were my fault, but all 3 had to have the floors removed, and rebuilt. all 3 was from the plumbers flange, 3 different plumbers were used by the homeowners. 2 leaked because the seal gave up on its own over time,(obviously they were not tight enough) plumbers had to pay me to redo. the 3rd I was paid by homeowner, because he admitted to plumber to using a toilet plunger to try and unclog the drain, that was full of hair. In doing so he blew out the seal, when the clog would not move. but there are more reasons than that. I have repeatedly been called in to redo showers here in the south (NC)because of mildew/mold. if you live in humid states rubber liners with wetbed is just not smart. it is just that a wetbed. Anyone can say what they want, seal it every year, or not the floor of a tile shower takes days/weeks to dry out after a shower. this combined with the fact that the floor and every wall contracts with temperature guarantees you that in a tile shower the corners Will crack no matter how small. relevent to leakage, no thats why the walls are sealed before the tile, it is enevitable that water will enter behind the tile in some small amounts. and move down to the pan. True they make caulking in every color that they make grout in, and should absolutly be used. but this does not take away from he fact that there is no possible way to keep water from getting under the tile level on a tile bottom shower floor. liners are not there incase the tile fails, its a working part of the shower system. and in this system (the cracks around the corners) there is an eco-system that is perfect for mold and mildew to survive, and spore out into the rest of your home continuously. cultured marble bases removes this continuous dampness, as well as having a standard flange that can be easily changed/worked on in case of any cause. Cultured marble pans are flanged on top, come in stardard sizes up to 4x5 feet, then you could build a bench all the way around the outside of that for a party shower. If you use cultured walls as well, corners are siliconed in, as well as a second sealed corner trim strip. so leakage is an impossibility, so is moisture retention. Recesses, and shelving no problem, even adding them later. smooth single no seamed surfaces are easy to clean and no maintainance. I make money if I do the tile, when I do bathroom remodels, I use outside contractor if they want the cultured marble and I make nothing for that. Facts are facts, I want my clients to get what they want, and what they need is info to make thier own decisions. Other people have said clean and dry your shower after use, I say what are they thinking. I want a VERY low maintainance place to get clean, not a place where I have to do maintainance every night, I wont dry me and the shower after every use. There is still the water in the cracks that you simply cannot get to to dry, along the bottom of the wall to floor seam. if you use the cultured marble base , and tile walls, you will have no worries as well, the possible problem is in the tile floor base.

We have a little bench. Our shower comes to a point at the far end and it is built into the corner, with a marble top and tiled front. Because it is small and the corner is tight, it's cramped for an adult to sit on; our kids can sit on it to get their feet washed, but it is mostly there (1) for my wife to put her feet on to shave her legs, and (2) to use that odd little space. We also put shampoo bottles etc. on it, since it is mostly out of sight. The only disadvantage I can think of is that marble can be rather cold to sit on, vs. teak. (One factor to consider is whether you will actually be sitting on it much or not.) (As for getting up, I had a disabled parent so I am familiar with the issues, and I don't think it's a big concern. Unlike a tile-topped bench, it's not flush; the marble top overhangs the front a bit.) I was a bit concerned that tile-cleaning chemicals could harm the marble, but there is no sign of that after 3 years.

How about just the bench and getting a great basket or tray (that drains) and putting your products in it? That way you can get both. This might work especially if the bench is at least partly shielded from view from outside, if you care about your products being out in the open. The niches are useful but they do take some extra cleaning and I have to say that I don't love them. (there have been threads on the value of niches--people have definite views!) The bench is a really nice look. I am not sure how much anyone really uses it to sit (maybe as I age, I will sing a different tune) but it is nice to prop up the leg when washing or shaving.

Sounds like you are potentially inviting a leaky shower by penetrating the barrier if you do that. Even with an originally-built bench, there are mixed feelings about potential long-term issues due to standing water sitting on the bench. You'll probably get a lot of votes on here for a nice teak bench in the shower. That's what I'd do.
