The meta-information for Bedrooms, Bathrooms, Garage, etc is displayed on several sections throughout RealHomes Theme. The icon used for these fields is an SVG icon so you can easily replace them.
The SVG icons are located in wp-content → themes → realhomes → assets → modern or classic or ultra → images → icons directory, Featured Property Widget icons can be changed from wp-content → plugins → Easy Real Estate → Images → Icons and if you are using Elementor then the icons in Elementor must be changed in wp-content → plugins → realhomes-elementor-addon → assets → icons folder.
Please note that you should also validate the SVG icon’s code by adding the required class to it and remove anything extra from it. For example, the Garage icon’s SVG code looks something like this:
Notice the rh_svg class so that what you have to add and some SVG icons have in them so simply remove it. If you want to change the Label for these meta fields then navigate to Dashboard → Appearance → Customize → Property Detail Page → Basics as shown here.
