Assuming you have decent cold water flow elsewhere and it’s the shower throttling it you could potentially get a more powerful shower.
Your current shower should have a rating on it somewhere, you may need to unscrew the front. If it’s 7 or 8kw then a 10kW+ new one will defo make a difference.
Potentially a job for an electrician tho, you’ll need to be sure the existing cabling is up to it.
