We just did a similar project Size comes into play - a walk in shower does not have to be the same dimensions as a tub/shower combo, so that can give you a little free play. And then you have to decide if you're going to buy a shower stall or create your own. You can buy shower liner, tile boards, and tile the entire shower. It sounds like you have a few decisions to make!

Unfortunately we often learn our lessons "the hard way", knowing that we'd do things differently "the next time"! I do reach out to friends before a big purchase, if only to ask if they've ever had a particular brand or used that store, so I find out if there have been major problems. I can think of a few things I bought after moving into this house, where I'd do things differently .. fortunately none are catastrophic problems! The other day I mentioned that to get chairs on casters for the dinette, I had to get them separately from the table .. and now I find the table slightly high for comfort .. I never thought to measure the relative heights of the chair seats in the store! I haven't been happy with the washing machine I bought either, but only realized that after using it .. so I'd never buy that brand again.

Just from pure preference I like H and I. The others are a bit busy for my taste.

I have glas shower doors like that and love them. My husband wasn't sold on the idea then one weekend I asked him to clean the track of old-style doors. He finished then said call the glass place on Monday.
