Bamboo is great for TP, and since the first NRDC report (mentioned in my other response which shows my comment has data behind it) shows the shift to using bamboo fibers in many major brands, too.

Personally, I find bamboo way better than recycled (and bamboo use vs tree use is perfectly sustainable, bamboo grows faster than it can be farmed). We find the brand we use comparable to Charmin "normal" paper (not the overly plush stuff). Happy to recommend a brand to try if asked, but don't want to sound like a shill/advert. Plenty out there on a search 😉

Also, don't negate a bidet.
