@Carson P.
Thanks so much for the insight Carson, very helpful information and perspective. Yes, it is my primary residence currently so I will indeed try to enjoy it! Wanted to get a feel for future value I’d derive upon lease and/or sale to see if it’d be worth to do. My plan was also to do the kitchen in the near future, so glad to hear some anectodotal evidence it is worth the investment.
Glad to know the quote is reasonable - I got an official estimate this afternoon actually and it is almost $11k for the master bath (new shower, tile, cabinets, flooring, countertops, toilet, baseboards). I have heard it is best practice to get at least 2-3 quotes before selecting a contractor, but I feel based on my interaction with this initial contractor he is trustworthy, reliable and can do good work for a fair price.
And yes, makes sense on the cost for tub replacement only versus shower since there is more tile and the glass itself for the shower is a few thousand!
Thanks again for the feedback!
