I have a small closet measuring 4x5 feet that I want to turn into a half bath, but I'm receiving a wide range of quotes from contractors. I'd like to know what I should expect to pay for the following: 1) Running the sewer pipe, water lines, electricity, and exhaust fan. 2) The above tasks plus installing tiles, a toilet, a sink, mirror, and lighting. 3) Alternatively, if I were to hire separate plumbers and electricians and do the finishing myself, what would the costs look like? Just to clarify, the closet is 4x5 feet, not 450 square feet as some are suggesting. Thank you!

To be honest, I think your quoted size is a bit of a head-scratcher. If it really is 4x5, we're talking more like 20 square feet, not 450. At 150 bucks per square foot, things can add up fast! But if it’s just a standard half bath conversion, you probably won't hit those crazy numbers unless you go all out with fancy finishes.
For a half bath conversion like yours, the costs can really vary. If you're looking at just the basics like running sewer and water, plus the electrical stuff, I'd estimate around $30k to $75k. On the lower end, you might get a basic acrylic tub and cheap flooring, while up to $75k could include nicer tile work. Just remember, that's if you're going for a full contractor job. If you go DIY for the finishing touches, you could save a bit by sourcing materials yourself!
Yeah, that sounds about right. I converted a small space a few years back and went the cheaper route too, and it turned out fine! Just make sure to shop around for deals on supplies.

Exactly! Unless you’re planning for a luxury makeover, stick with a realistic budget. You can do quite a bit for a smaller dimension without spending a fortune.
