ᐅ Is it feasible for a layperson to install baseboards themselves?

Hello,
we have hired a painter for the entire house, including wallpapering and painting. I have now asked what he would charge for the baseboards but haven’t received a price yet.
Is it something a layperson could realistically do themselves? A miter box and a Japanese saw can be bought for about €70 (around $75). On Amazon, there are complete kits with baseboards and corner blocks available for just under €200 (about $215), although I haven’t calculated if the length would be enough. However, a friend mentioned that installing baseboards is much more difficult than it seems at first glance. Especially cutting for the corners would be a really tough job.
Do you have any experience with this? I’m not extremely perfectionistic, but it should look neat. Would you recommend letting a professional handle it, or is it something one can try doing oneself?

It’s a simple task if you take care at the corners.
What kind of baseboards do you want? Then we can give you a better answer.

We did it ourselves. Used a miter saw for the corners and attached the pieces with mounting adhesive from a cartridge or silicone glue.

We were thinking of using MDF moldings (which are widely available online); they look white but are not real wood. I like the Hamburger or Altberliner profile best. For damp rooms, I assume we would need to buy special moldings?

Wet rooms should have a tile baseboard if they are genuinely damp. Bathrooms and possibly the utility room. For me, the kitchen is not a wet room.
Our baseboards are also made of MDF.

Yes, this is exactly what we are looking for. Can someone without professional experience handle the corners properly? The tool I saw is placed on the respective corner to set the angle for cutting. It sounds simple at first.
