Here’s an inside look of the shower at the bathroom project. We used @tilebar 24x48 ribbon tile, @bedrosianstile 2” rounds on the floor, and @kohler Purist fixtures to finish it off 👌 • Designer: @tinyanchorstudios @egiambri06 Installation: Keystone Home Remodeling • • • • #bathroom #tile #construction #pennsylvania #homeimprovement #homeremodel #design

Another view of our bathroom project! The old soaking tub (swipe —>) was pretty much the catalyst for kicking off this whole project. When it started leaking, since it was used very often by the customer, that led them to start exploring a redesign of the whole space. • Designer: @tinyanchorstudios @egiambri06 Cabinetry: @shcabinetry Tub: @mti_baths Juliet • • • • #construction #pennsylvania #bathroom #design

We just wrapped up this mudroom that was converted from the old laundry room. It made more sense to have the mudroom right off of the the garage and to move the laundry to the second floor. • Cabinetry: TL King Cabinetry Design: @tinyanchorstudios Tile: @tilebyvince • • • • #mudroom #homeimprovement #construction #contractor #mediapennsylvania #cabinetry #interiordesign #tile

Another view of our West Chester hall bathroom project. Some nice details in this bathroom include a custom two-piece crown and casing to enhance the look of this small space. The custom vanity by @shcabinetry in @sherwinwilliams Messenger Bag gave a nice subtle contrast among the other earth tones we incorporated into this project! • • • • #bathroom #westchester #construction #homeimprovement #homeremodel #remodeling #design #interiordesign #cabinetry #pennsylvania

I love how this kids hall bath turned out! We were waiting on a couple back ordered items that finally arrived to wrap this one up. The customer designed this one themselves and I think they did a great job! • • • • #bathroom #renovation #homeimprovement #homeremodeling #remodel #home #construction #contractor #pennsylvania

Another great master bathroom project underway. I won’t say this photo shows it “fully demo’d” because it always seems like there’s an hour here and there doing more selective demo the week to follow. This should be a great transformation!

Didn’t quite get this one across the finish line before the Christmas break, but made some decent progress. The customer has made some nice material choices so far to class up this bathroom including handmade @sonomatilemakers tile and @floridatile wood plank tile, @kuikenbrothers mouldings, and a @kohler Archer tub. Can’t wait to reveal the finished space. • • • • #bathroom #bathroomdesign #bathroomremodel #construction #homeimprovement #renovation #remodel #contractor #design #interiordesign #westchester #pennsylvania

I forgot about this pretty cool find when I renovated my in-law’s 1903 kitchen back in 2016. This quarter from 1894 has 90% silver content and is worth about $15 in average condition, but could be worth hundreds in mint condition (from what I’ve seen online). • • • • #oldcurrency #american #quarter

6,100 lbs of debris removed from the 100 year old 6x10 bathroom. We stole a small closet from the office to expand the footprint slightly. Lots of work ahead of us!

Besides the land/hardscaping, this backyard office build is complete. We decided not to cheap out and went with all pvc trim and corner boards, pre painted hardie siding, Andersen windows, epdm roof, all spray foam insulation, and a Mitsubishi heat pump split system. I think the door color gives it a nice pop against the iron gray siding 😊. • • • #backyardoffice #office #backyard

Here we took the laundry from the first floor and moved it to the master bedroom walk-in closet. We repurposed a sitting room in the master bedroom as the new closet by narrowing the opening and installing a California Closet system. The downstairs laundry room will now be converted into a mudroom. • • • • #laundryroom #laundry #mudroom #renovation #homeimprovement #construction
