Alchemy Materials

Alchemy Materials occupies the fourth floor of 20 West Twenty-second Street, a long-standing building where commercial strips meet loft living. Tile shops remain the place for spot-on deliveries and stone samples the size of placemats. Drop by to puzzle over veining and finish swatches; they compare Andalusian micaceous to a Brooklyn beige in daylight. Need slabs cut down to trim size—ask them. The place also quotes shop drawings for fireplaces and full-height shower surrounds; quotes take one business day. If you’re inside already, a staffer will annotate a plan set in real time while you wait.

All work is wrapped in a 30-day service guarantee—not coverage, just the guarantee, so you know any bad cuts or mismatches get retouched or remade under the same roof. Parking is metered Broadway to Sixth and residential permits south if you luck out; ride the F/M/23 on weekdays for one stop to 23rd. Take elevators to 412, buzz, and it’s open. Doors open promptly at 9, but nobody calls about after-hours projects anymore.

Dial (212) 929-7293 for price checks or to leave a sketch for next-day cutter time; voicemail picks up after hours. A quick map and route planner live here.
