I think we've hit rock bottom. This is officially the worst any part of our house has ever looked.
We're hiring out the plumbing for the drains which will be in the new bathroom and new laundry room sink. Doing the vents right can get tricky and we don't want our first DIY plumbing job to be covered in sand and concrete. If it starts leaking in a year it would be a pretty big mess to fix. This falls under the "over our heads" rule on our DIY vs. hire out criteria.
Plumbing is going to be the most expensive part of our basement renovation but to lighten the load we jack hammered the concrete and dug out all the dirt ourselves. Once the drains are in we'll put the sand back around the drains and pour concerete on top. Yikes. This is a lot of work for a toilet, sink, and shower. We hope it's worth it!
