One Tumbler.
Two Sizes.

The patent pending modular tumbler that transforms between 12oz and 20oz in seconds.

The Problem

Sound Familiar?

A cabinet shelf that's basically a tumbler graveyard.

Buying the small tumbler, then wishing you'd gotten the bigger one. (Or vice versa.)

A tumbler that's too tall for your coffee machine, too wide for your cupholder, and somehow still hard to clean.

We Made One That Fixes It All.

Why Sunaba

We Obsessed So You Don't Have To.

Your Cabinet Called. It Wants Its Space Back.

That collection of tumblers you swore you needed? Replace them.

One well-designed piece does what several mediocre ones couldn't.

You're welcome, cabinet.

Fits Where It Matters.

At just over 5 inches tall, the 12 oz configuration fits under every Keurig and most Nespresso machines. Both sizes fit standard car cupholders.

We measured. Multiple times.

Designed for Hands,
Not Hashtags.

Clean lines. Thoughtful ergonomics. A 360° drink lid that works from any angle.

This is what happens when a tumbler is designed around your day, not around a photoshoot.

Takes Apart in Seconds.
Cleans Like It Means It.

Wide openings. Minimal parts. No tiny crevices where yesterday's coffee sets up camp and starts a new life. Disassemble, wash, done.

No bottle brush gymnastics required.

Our Story

About Sunaba

We have spent our careers designing and building consumer products for other companies. The goal was always the next sale. The result was always the same: people owned more than they needed and used less than they planned.

We started Sunaba to make fewer, better things that earn their place.

Designed for people who choose how they live, not just what they buy.
