Has anyone swapped to a combi boiler?

[Wysterialane]

House currently has 2 bathrooms, 1 shower 1 bath. We are redoing our bathroom and want to put a second shower in.

The room is a super awkward shape due to the airing cupboard and getting rid of it would mean we could have separate bath and shower. However I’m nervous about the impact on water pressure. The house has a fairly sizeable footprint if that makes any difference.

Has anyone done this and can you have 2 showers at once etc?

We don’t have a second shower but we replaced our old combi boiler with a new one and went for a bigger size, now when the kitchen tap goes on the shower pressure only drops slightly and does not go cold like it did with the old one. I would get a boiler company in and tell them what you want to run off it and what size they would recommend.
