WiFi for garden room/shed

iazcac

In process of building a garden room (glorified shed!! ) at bottom of garden as a home office. It's about 20metres from house.
I want to have WiFi down there but too far from house for normal connection. Intend on putting a wired connection in for laptop, but also want WiFi for smart speaker, tablet etc.
Is it possible to connect a second router in shed from my main router via some ethernet cable laid in garden. 
Looked at mesh WiFi but looks fully wireless and not sure would stretch 20m gap from house to shed
Any ideas on what best  set up would be? Thanks in advance

Homeplug could be an option, a cheap network switch and a wireless access point.

You can lay ethernet cable around the garden, but it has caveats.  Ordinary Ethernet cabling deteriorates quickly when exposed to the elements. Exterior-grade Ethernet cables are waterproof and can be buried in the ground without a conduit. If you aren't burying the cable, choose a waterproof Cat 6 cable that has a UV protective jacket to prevent damage from sunlight exposure. This is important when running the cable up the side of a house or across a roof.

This is worth a read:

Lots of good info above about the ethernet cable.  At the end of the cable could do this...
