Spa Day is the only pack for Sims 4 I haven't purchased (I'm not sure why). I noticed it's on sale right now, but the only thing that immediately makes me want to get it is the hair to be honest. Othe...
I think its worth it. I use the build/buy items the most, especially the tables and chairs, i have some in almost every house i build. I don't use the spas to much really. I always add yoga mats to gyms though, and at least 1 full spa. I like doing a spa day before a wedding too.
