You can get a Shatfa or "bum gun" installed next to your toilet instead, if you can't get power for an on-seat bidet instead.

They are very common in the Middle East.

Personally I wouldn't do without one and would install one in any new home I moved to.

Every one of them I've seen was the cause of a large puddle on the floor next to the toilet. I've only seen them in India and so this might be a statement on infrastructure in India. They are all over in India and they all leak, so I'm not interested in having one in my house.

I rented a house in London owned by a Muslim family, and the toilets had the spray things and no puddles.
