replacement internal door

[tearinghair]

I need to find an internal door to replace a bedroom door. The original (and all the others on the landing) are plain (house built in 1958). Homebase seem only to have panelled doors - 4, 6 and even 8 panels - and they are quite heavy. Our local branch of Focus is one of those which have just closed. I don't know where else to look - will it have to be a builders' merchant? Ideally would like it to be pre-painted (white), or at least primed.
Any advice would be welcome. Many thanks.

Mr Tearing .............. standard plywood flush door (paint grade), I guess.

Usually in stock at the main builders' merchants.

Thanks Builder, that looks fine. I didn't think of ordering online, but with that amount of detail I'm sure I can find the right one. (It's Mrs th, not Mr, btw - I'm the one that uses the computer, OH is the one who'll have to fix it!)
