Replacing an internal door like for like

In our new (to us) house a bedroom door needs replacing. It has been previously repaired but is warped (looks like someone kicked it in!).

The current doors are basic Jeld-Wen 35mm thick white doors. Would it be straightforward enough to buy a replacement and use the existing door as a template for hinges and latch?

If it is simple, I’m half tempted to do all the doors as I don’t really like the style of them, plus they are very thin (possibly hollow core).

Current hinges on all door, I’d be reusing these

If it’s a standard size and the frame is still square it’s a doddle. Easier to hang doors if you’ve got a second body. Pop some cardboard or 3mm ply or something underneath when you do it to make sure it’s not dragging on the ground.

There’s also some guides you buy to make sure hinges are spot on, frame/door line up, they are great but expensive, although if you are doing all of the doors maybe worth it

If it’s a weird size it’s still easyish to do but involves a custom made door. If the frame is squint it’s going to be a right pain in the bottom. I made a door for my bike shed, the door aperture is nowhere near square, actually found it really satisfying to do, took a couple of days.

Relatively easy to do if you have some DIY skills  I replaced similar downstairs doors with oak veneer. You will probably need to plane the new doors to make them fit, there’s no guarantee the frames will be straight or square.
