Studio & Showroom · Est. 2014
Tiles, stone, and floors specified by people who finish what they specify.
Datumly works with homeowners, contractors, and design studios across the Peninsula to source porcelain, natural stone, and engineered flooring — and to install them with the care they were meant to be installed with.
Studio specification.
From sample to grout joint.

What we work with
Five disciplines, one studio.
Each category in the showroom is curated by a specifier who actually installs it. We carry what we'd put in our own homes — nothing else makes it onto the floor.
Flooring
Wide-Plank & Engineered
European oak, smoked walnut, and engineered hardwood in plank widths up to 11″, finished to spec at our partner mills.

About the studio
Why a small studio
01
02
03
One specification, handled end to end.
Most material runs go wrong in the gaps between three vendors — the tile shop, the installer, and the trim package. We close those gaps by carrying the material, scheduling the install, and standing behind both.
Specifier-led
Every floor on display is here because someone on staff has installed it. Not because the rep had stock.
Sourced, not stocked
Direct relationships with European and Pacific Northwest mills mean we can pull from full ranges, not just bestsellers.
Installation tied to material
Our crews finish what we sell. One number to call when a grout colour, a transition, or a delivery slips.
How a project moves through the studio
Four stages, one continuous specification.
Brief & site read
A 30-minute call to understand the build, the budget envelope, and the rooms that will see real use.
Studio session
A working visit with full-size mock-ups and a paletted shortlist drawn from the live ranges we can deliver.
Sourced specification
A written specification with mill, batch, lead time, trim package, and the installer who will actually lay it.
Installed & documented
In-house crews finish the work. We hand over a closeout file with batch numbers and care notes for resale.
From the studio
What clients have told us.
“Datumly was the only specifier in the Bay Area who walked the framing before quoting tile. The waterproofing detail they drew up saved a 1924 ceiling we love.”

Marisol & Reuben H.
Burlingame, primary residence
“We kept hitting backorders on a porcelain we'd specified twice before. Datumly pulled an alternate from the same Sassuolo mill and matched the colour on a Saturday. The crew arrived Monday.”

Priya T., AIA
Architect, San Francisco
“I run a small build firm. Having one specifier carry the porcelain, the wood, and the tapware — and stand behind the install — is, frankly, the difference between a calm Friday and a bad Friday.”

Common questions
Before you walk in.
Do I need an appointment to visit the showroom?
Walk-ins are welcome during studio hours, but for serious specification work we recommend booking a 90-minute studio session. It guarantees a senior specifier, a working table, and time with the sample library uninterrupted.
Do you sell to homeowners directly, or only through trade?
Both. About a third of our work is direct-to-homeowner, often when there is no architect on the project or when the architect prefers to outsource finish specification. Trade pricing is honoured for licensed designers and contractors.
Can you install material I've already purchased elsewhere?
In limited cases, yes — but we'll first inspect the material and the substrate, and the warranty terms differ. Most of our installation work is on material we've supplied, because we're accountable for both halves.
What kinds of projects do you typically take on?
Residential renovations and ground-up homes between roughly 1,200 and 9,000 square feet. We also work on small commercial projects: boutique hospitality, clinics, and offices where finish quality is part of the brief.
How far in advance should we engage the studio?
For specification, four to eight weeks before tile day on the schedule is comfortable. For installation, eight to twelve weeks for the senior crews, sooner for spot work. European porcelain lead times have stabilised but still run six to ten weeks.
Do you provide written specifications and budgets?
Yes. After a studio session we provide a written specification with mill, batch, lead time, trim package, and an itemised budget. It is yours to use whether or not you proceed with us for installation.
Walk into a working studio, leave with a real plan.
Tell us about the rooms you're finishing and the calendar you're working against. We'll suggest a studio time and the right specifier to sit with.
