Having a shower is not keeping up with them;
Getting your whole shower/bathroom redone and telling everyone it cost $30k (or more) is.
Also known as "subliminal brag" -
Would normally be dropped into the conversation in this manner;
You: "Got the bathroom redone last month; turned out pretty good."
Friend: "Oh really?"
You: "Yeah; the b@stards wanted to sting me fifty large for it, but I got 'em down to $35k".
You should reply "I got ripped off on my bathroom too, they did a good job and they charged me 3k!!!"
