Hi, unless you take a bath at least once a week I'd skip the tub. I'd rather enjoy a bigger walk in shower, which is also a lot safer than climbing into a tub to shower. If you have the space instead of a tub and shower I'd consider a double vanity to give you extra storage space. It's a little luxury you will come to enjoy when everyone is getting ready on the morning.

Agree it is hotly debated. In our first home we renovated we had a big bathroom, double shower, clawfoot bath, double vanity. Our laundry was right outside our bathroom and we decided instead of having a change table for our babies, we would put a mat on the laundry bench and use that, much to several of our friends dismay who promtply delcared we would get sick of it after 5 minutes and do the changetable in the nursery. Um nope, never did and used the laundry bench the whole time, actually made cleaning up several 'poonamis' as we used to refer to them as, rather easy actually. In the end, both children ended up bathing in our laundry tub, no kneeling down and bending over a bath, and right next to our designated 'changing station' lol, and it worked perfectly. Failing that we would often shower the kids, we had a bumbo that we put in the shower with us and they would sit in that, loved it. As they got older as toddlers, both used to shower a lot and not use the bath at all. We left that house when our eldest was 7 and our youngest was 4. We went on to purchase and renovate another house that never had the bath put in until we were nearly finished the reno and were selling, so no baths there either. Now we are in their (the kids) third house since they were born and they are 12 and 9, small bathroom layout, they've had baths here a few times...but not a lot. And now like you we are debating...when we redo this bathroom...to bath or not to bath...lol. Not sure if it helps... :)

Depends from size of the tile. Full tile between edge of the bath and bottom of the niche looks better, If you are planning mitre around the niche.

I have a glass screen for a shower bath combo. It’s attached to the wall with two hinges and a row of silicone at the base of the glass where it sits on the bath. I would say that a decent amount of the weight of the glass rests on the bath edge. So not suitable for your setup. If you talk to the installer, they may have wall fixing that run the length of the glass and hold the entire weight of the glass. You would still have water escaping through the gap.
