What size accessories do I need for the Gaggia Classic Pro?

The Gaggia Classic Pro and Gaggia Classic E24 use a 58mm, 3-ear commercial-style grouphead. You need 58mm portafilters, tampers, puck screens and dosing accessories.

Is the Gaggia High Diffusion Shower Screen worth it?

Yes — it's one of the most well-regarded upgrades in the Gaggia community. The precision-engineered hole pattern distributes water more evenly across the coffee puck than the stock screen, reducing channelling and improving extraction consistency.

What is the best first upgrade for a Gaggia Classic Pro?

A 58mm bottomless portafilter is the most impactful first upgrade. It gives you full extraction visibility so you can diagnose and fix channelling, grind and tamp issues quickly. Pair it with a proper 58mm tamper and distributor for the biggest improvement in shot consistency.

Are Gaggia Classic Pro and E24 accessories the same?

Yes — the Gaggia Classic E24 is the latest version of the Classic Pro and uses the same 58mm, 3-ear grouphead. All accessories compatible with the Classic Pro are also compatible with the E24.

What should I upgrade first? +

Gaggia High Diffusion Shower Screen — A precision-engineered replacement for the stock Gaggia shower screen. Distributes water more evenly across the puck for better extraction consistency — a well-regarded upgrade in the Gaggia community.

58mm Tamper & Distributor — If you're still using the stock Gaggia tamper, a proper 58mm barista-grade tamper paired with a distributor makes an immediate difference. Our 2-in-1 tamper and distributor combo is particularly popular with Gaggia Classic owners.
