This was exactly what my tub/shower needed to get it out of 1972. I am VERY glad that the pictures and description said it required the Delta MultiChoice Universal Mixing Rough-In Valve with Service Stops (sold separately) because my plumber could not have installed it without that piece. I found out the hard way when I ordered another unit for a shower and had to rush to one of the big box stores and repurchase something. If you purchase this set make sure you get the rough-in valve to go with it!!!!
