untippable
Resistant to tipping
Something untippable cannot be tipped over—designed or positioned to resist toppling: The weighted base makes the cup untippable.
The word also describes someone who cannot be tipped in the gratuity sense, either because tipping is prohibited or because the person refuses: The concierge was famously untippable.
